Well that brings an end to an exhilarating day of play on day two at the Ryder Cup. United States are five points from victory with Europe on the brink. Join us tomorrow for live coverage of the singles competition from 11am/5pm on Sunday. But until then, goodbye.
America take the point as Reed cosies up to the hole. United States claim a 3-1 victory in the fourballs and that will surely prove fatal in Europe's attempts to retain the Ryder Cup.
The final group are going down 17 and Reed is in the box seat again, within seven feet. Rose and Stenson in the vicinity too but it is advantage USA. A halve will do to claim the point. Rose misses to the right, leaving Stenson with a do or die putt. The Swede shaves the left edge and the US have two putts to win the match.
Match four not over yet. Henrik Stenson chips in off the green to give Europe hope. Reed still has an eagle putt to claim the halve and the point in this match but he's short and the US' lead is down to two.
Westwood misses! United States claim the point. What a moment in this match.
All eyes on Lee Westwood now at the 18th. The US have two shots for birdie from off the green to win the match. Moore is nowhere with his shot, fully 15 feet short. Now Holmes has left it short too. Willett misses his birdie attempt and it's all on Westwood. Three feet to secure a crucial, crucial halve.
Garcia makes the birdie at the 17th. Mickelson can win the match however with a putt from around six feet and it will put the USA back ahead. He takes a big intake of breath and makes the putt. USA claim the point.
Danny Willett keeps Europe alive in match two and Lee Westwood completes the trick, leaving it stone dead at 18. That is a surefire birdie and the US must respond.
Reed makes another putt in what has been a stunning round and the US have a guaranteed halve in the bottom match. They lead by three with three holes left.
Stenson's putt goes by at the 15th and Reed will have a putt to secure a three hole lead and at least a halve.
Sergio Garcia goes to within three feet at the 17th! Amazing shot just when Europe needed it. Two down with two to play but that is a near-gimmie.
Willett misses his par putt and now Westwood must drag Europe out of a hole. He must make his three or Europe will be one down going down the 18th. He misses and USA are now up in three matches.
Ryan Moore comes up short with his birdie chance at the 17th. Willett is off the green but has a shot to secure at least a half and put Europe ahead. It's horribly short and now they have a putt to save their half. Reckless stuff from the holders.
Now these eagle putts for Europe. Sergio Garcia comes up a foot short and that is a birdie. Kaymer will have his eagle chance now, knowing he can take this to the 17th if he makes it. The German kept the match alive on the last hole put is a bad miss but Kuchar can't take advantage and Europe reduce the lead to two.
Phil Mickelson makes a mess of his bunker shot on 16 and Europe looking good to get another shot back here. Kuchar is now on the green after laying up. Jordan Spieth meanwhile has gone into someone's back garden from the tee at 15.
Both European players have putts for eagle and to go two behind Mickelson and Kuchar at the 16th.
J.B Holmes finds the water at 17, piling the pressure on Ryan Moore.
Justin Rose putts first for birdie at the 14th, but he misses short. Westwood also misses from three feet on the 16th. Danny Willett's eagle putt is now a two-putt for birdie, with thoughts of winning the hole totally gone. The green jacket winner comes up three feet short and that really wasn't what was required, but he makes the second.
Stenson misses his birdie putt for Europe back on 14 and it gives Reed a chance to put the US two-up, and it's there. That was a gift from the Europeans.
Spieth chips from the bunker but there is still six feet to make up there. Holmes produces a fine chip to go inside Westwood, but Willett has a put to win the hole on that 16th.
Lee Westwood chips brilliantly from the bunker to within three feet. Europe have won par, but can Holmes repeat the feat from the same position?
Sublime from Justin Rose, who goes to within 20 feet on the green. Can Stenson lay the platform for a birdie? He swings with reckless abandone but he's inside 12 feet and there are two birdie chances there.
Ryan Moore meanwhile hits to the front of the water and narrowly evades going in the lake. Advantage to Europe there.
Back on the 14th in match four, Spieth is in the sand.
Willett goes safe at the 16th. Now Westwood from the middle of the fairway but he finds the bunker on the same side. The Masters champion in a good spot there. I've written this maybe a hundred times in the afternoon session, but this is a massive match in the context of the whole week. J.B. Holmes in the first cut of rough and he finds the bunker alongside Westwood.
Kaymer and Garcia have putts to save the hole, though USA will be dormie three at worst. The Spaniard goes first from the edge of the green and it shaves the right of the hole. Kaymer next and it is about time he made a valuable contribution. He has an eight footer and he makes it. Europe still alive in this match, but the half if secure for the home side.
Mickelson putting for the win at the 15th. A birdie will all but win the match and put the USA ahead again and Hazeltine goes made and he makes another putt.
More good news for Europe as Rose's birdie ensures Europe go within one of Spieth and Reed, who having played all three sessions look spent once again. Five holes left in that match.
Koepka misses to the left at the 17th and is that it for the United States? Pieters' putt is not conceded and he will putt for the match. He needs just one putt and Europe have the point in the top match. Not clear cut but a point nonetheless in match number one.
Ryan Moore misses a huge chance to put the USA ahead in match two. They're all squad down the final three holes. Birdie chances coming up however.
Matt Kuchar celebrates putting USA into the ascendancy on day two.
Brilliant from J.B. Holmes who finds the green at the 15th. Brooks Koepka does similar at the 17th in match one, but Johnson all-but finds the water. Can Pieters or McIlroy finish this match? The Belgian goes to within five feet, and that might be good enough.
Kaymer misses for birdie and Mickelson's putt puts USA three up with four to play in match three. This session moving away from Europe here.
Henrik Stenson with a birdie to win the 12th and reduce Spieth and Reed's lead to two.
Martin Kaymer matches Phil Mickelson's approach at the 14th. Now back to the 16th where Johnson will putt for the win first, but he misses to the left. Pieters will be asked to putt, which he does successfully. Koepka has a two-footer to take the match to the 17th, and he duly converts too. Europe not home and dry yet.
Koepka all-but makes the birdie for the US as his eagle putt comes up short. Pieters will have a chip to win the match, but it goes by. This match is going to two.
Westwood plays a beautiful approach but can't convert the birdie chance. Back to 16 and Thomas Pieters can't stay on the green. Koepka will have a putt to win the hole and take the match to the 17th.
Are Europe about to throw away a position of strength? McIlroy finds the water at the 16th. Dustin Johnson doesn't take advantage as he goes towards the water, but in the rough. Down to Thomas Pieters to secure this point.
And Garcia can't match Kuchar's effort and America are two-up.
Sergio Garcia with a chance to go birdie-birdie at the 13th. Kuchar will go first and he produced the business, Fabulous effort and the US are set to go two up. Garcia's putt now to halve the hole.
Patrick Reed has been a putting machine this afternoon but he misses the chance to put him and Spieth four up. They go to the 12th after Stenson too missed his birdie chance, after a member of the crowd shouting out as he addressed the ball. Another sour incident this afternoon.
Brooks Koepka with a chance to keep match one alive but he goes four feet past, giving Pieters the chance to secure the point. The Belgian draws the putter back but the ball funnels to the left and it's a miss.
The beauty of matchplay means now its the turn of Johnson. he has to make it to take the match to the 16th. The best player in the world right now rattled it into the hole and the deficit is reduced to three. That elusive point continues to evade Europe.
Sergio Garcia puts Europe back in contention in match three with a birdie from 30 feet. Mickelson can make the halve, but he misses and the US lead is cut to one.
Meanwhile in match two J.B. Holmes has a putt for the win, after Willett misses his birdie chance. He holes it and the hosts are back level.
Rose can't secure the half and now it's left to Stenson from around three feet. The Swede makes it to give Europe a glimmer in the bottom match.
Two misses in as many seconds. Garcia misses to the left to win the hole at the 11th in the third match, while Stenson goes by at the 10th in match four. Patrick Reed has a putt to put USA four up with eight to play, but he misses to the left. Europe still have to putt for a halve.
I've mentioned it a few times but match two is massive in the context of the destination of the Ryder Cup. Westwood's second shot finds the middle of the green and he will have a 30-feet putt for a birdie.
At the 10th meanwhile, Rose chips aggressively but way past the hole and it's left to Stenson to win the hole.
Koepka goes right with his putt however and Europe are back to three up in the top match. Three up with five to play.
Europe's lead in the top match is back to two but Thomas Pieters holes for birdie on the 13th and that will force Koepka and Johnson to putt for a halve.
Johnson is in the first cut of rough off the green and he needs a delicate chip here. Left short by the PGA player of the year however.
Danny Willett keeps Europe one up in the second match. With the United States having a cushion in matches three and four, this is a critical match for the holders, if they want to be in touch come day three.
Chance to get a shot back at the ninth for the final group. Justin Rose from around 10 feet can bring Europe to two down, but it shaves the front and the USA survive.
Phil Mickelson produces more brilliance, this time on the 10th. From a good 25 feet he drops it in and America go two up in match three. Kaymer and Garcia can't respond.
Rory McIlroy having a lean spell and he sends a chip beyond the pin at the 12th. The middle two matches look pivotal at this stage and the United States can win one of them, they will probably lead come the final day.
The reports of mischief from the crowd have been entwined with accounts of what a great atmosphere it has been at Hazeltine this afternoon. My experience has only been good, with sly comments coming amid and superb roars and cheers for good golf, as much as American success.
Pieters and McIlroy have again led Europe's charge in the second afternoon.
Lee Westwood, that is stunning. He turns in a putt from 20 feet and Europe are back to 1UP in the second match. What an improvement from the Englishman.
McIlroy gives USA a glimmer in the top match, as their lead is reduced to three through 11 holes.
Dustin Johnson plays out of the sand and USA still in contention for a half on the 11th. Koepka's chip is a poor one, seven feet past.
Meanwhile, at the eighth America about to go three up it seems. Reed has been sublime and he makes another birdie. He's gone birdie-eagle-birdie-birdie. USA three up in that bottom match.
J.B. Holmes rolls in for birdie on the ninth and that brings match two all square. Ten birdies from the front nine from these two groups, stunning entertainment.
Patrick Reed has hit a hot streak and he makes birdie at the seventh to extend the American lead, which stands at two.
McIlroy halves the 10th with a fine putt and he reacts to the American jibes, with a chorus of boos coming his way. Despite that, there is a a bit of American momentum out there at the moment.
Justin Rose short from his second at the seventh, having avoided the water, but he's in better shape that Reed. J.B. Holmes recovers well having found one of the main stands at the ninth and he's on the green.
Lots of talk already moving to tomorrow, and how Europe may line up for the singles. It's looking like it's going to be tight regardless of the overall score come the end of the day.
Rory McIlroy looking to end this top match as soon as possible, and he goes to within five feet with a fine second shot at the 10th. Koepka responds with an outstanding approach and that is as good as a gimmie.
Martin Kaymer dumps the ball on the green for Europe in a belated contribution. water trouble on the seventh for both Jordan Spieth and Henrik Stenson, whose ball takes several bounces before ending up in the creak. Many players have fallen into that trap today.
Elsewhere, McIlroy converts the birdie and Europe go four up in the top match. A point incoming there.
Wonderful from Patrick Reed! He finds the hole from his approach at the sixth and that is enough to move the USA one up in the final match. That is stunning and Reed knows it, going mad as the ball goes under.
More on the incident which saw a fan ejected for abusing Rory McIlroy.
Rory McIlroy is playing on a different planet right now and he's within two with a wonderful approach at the ninth. That is a surefire birdie, though it is yet to be conceded. Johnson and Kuchar need to hole one of their putts to ensure they don't fall four behind.
The Hazeltine crowd are continues to cross the line between heckling and abuse during the fourth session of the 41st Ryder Cup.
Match three is at the seventh where Sergio Garcia has gone down the right, away from the creak and is in the first cut of rough.
Off to the eighth where Lee Westwood, who is vastly improved from the horror show that was the opening session on day one, finds the green at the par three.
Lee Westwood puts Europe one up on the seventh. The ball that has remained dry is enough to give the holders the advantage in match two. A fine blow from around 18 feet.
Sergio Garcia with a putt to draw Europe back to one down in match three, but the chance comes and goes. United States have both balls in the creak in match two at the seventh meanwhile, but Danny Willett has also found the water after his second shot beat the green.
Henrik Stenson concedes Jordan Spieth's put at the fifth and USA draw level in the bottom match. So the United States are up in one, down in one and all square in the other two matches.

Westwood with a fourth European birdie and he halves the sixth hole, after Ryan Moore made a four. Europe covering every move by the United States so far.
Just an indication as to the animosity at Hazeltine.
Wonderful pitch from Westwood off the green to within eight feet at the sixth. Six birdies in five holes between the two teams in match two. It has a birdie fest in the afternoon.
Matt Kuchar keeps USA two up in match number three with a three on the 5th.
Genius from McIlroy, who holes brilliantly from 15 feet. He turns to Hazeltine lake and celebrates, before turning back to the crowd. Two putts for the USA to survive going three down. Dustin Johnson can't make the half, catching the edge of the left-side of the hole.
Now it's Koepka who is significantly closer and he makes it to secure the half. Big moment in this top match but Europe stay two ahead.
Much to consider for United States captain Davis Love, whose team have claimed just 1 1/2 points since the end of session one.
Phil Mickelson goes through the back of the green on the 5th, into the crowd where his lie could be anything. McIlroy is on the seventh, down the left having avoided the water, but his approach to the green is far from ideal and he's 20 feet from the hole.
Lee Westwood with a birdie at the fifth. Match two all-square through five holes. That already looks like the pivotal contest of the session with birdies having come as three of the five holes.
Garcia out of a whole after missing a birdie putt, as Matt Kuchar goes to the right with a chance to win the hole. Or is he? The Spaniard misses going back the other way and USA are two up in match three.
Justin Rose goes within a foot or so at the third and that is pretty much a gimmie for birdie. Big pressure approach that was. Patrick Reed has a putt for eagle meanwhile.
Birdie putt for Pieters and he makes it look so easy. Johnson's putt is conceded so that is another half for Europe through six holes, in which they lead by six.
Dustin Johnson goes within two feet at the sixth, in a match Europe are leading by two. A certain birdie there which will surely be conceded.
Disbelief on the faces of Garcia and Kaymer, who both find the lip of the third hole and that sees USA go one-up in the third match.
Phil Mickelson has been anything but at his best but he produced s slice of genius with a fine chip at the third, which secures a birdie as he goes within a foot. USA set to go one-up in the third match.

Thomas Pieters is excelling on debut here and he makes a fine eagle on the par four fifth to put Europe two-up. That has been a dreamboat pair for Darren Clarke.
Well, well. Brooks Koepka's drive goes into crowd and has lodged itself on the bag of a spectator. But not just any spectator, but Thomas Pieters' father whose son is playing in this fourballs match. Koepka gets a free drop. You'll remember Rafa Cabrera Bello drove into the pocket of the fan during the foursomes.
Europe one up in the bottom match thanks to a birdie from Henrik Stenson. J.B. Holmes puts USA on the brink of going up in the second match, but Danny Willett responds with a fine birdie.
Justin Rose spins his ball back to within eight feet at the first. Hard to know where to look at the moment, such is the regularity of the birdie chances. Pieters lets one go by however, to give USA the chance to square the match through four holes. Koepka can't get it to drop however and Europe remain ahead.
It has been a stunning start to the fourballs. Rory McIlroy somehow doesn't chip in on the third. Now Sergio Garcia takes aim and he's within five feet at the second.
Lots of American fans wanting to be the centre of attention this week.
Thomas Pieters with his first genuine contribution in the fourballs and he secured at least a half from the third. Koepka must reply, and he does as another hole is halved in birdies.
Kuchar means makes his birdie and that is a second hole halved in birdies. The quality of golf is outstanding, given what is at stake.
Danny Willett chips in! Off the green on the downslope and he nails it on the second. Fabulous from the Masters champion. J.B Holmes responds with a 15-feet putt of his own. Fabulous golf.
Nice chip from Rory McIlroy, who is starting to emerge as the outstanding player on the European team. Brooks Koepka makes no mistake however and he's within eight feet.
Matt Kuchar with a miraculous approach into the 1st. Kaymer usurped and Europe will need a birdie if they're to stay all-square.
That's much better from Martin Kaymer who finds the green from the middle of the fairway. Lee Westwood does the same from group two, and he's within 15 feet.
Match three has been sightly delayed but is underway now and it is advantage to the USA with Mickelson and Kuchar both on the fairway. Martin Kaymer is in that group, and he'll be wanting to improve on what was a horrid round yesterday.
Westwood with a putt to win the hole but he sends it too far out right and the chance is gone. Willett ensures the hole is halved. Big match for these two, after they struggled yesterday.
Koepka fails with his chip off the green and Johnson goes by his birdie putt. Europe one up through two in the first match. McIlroy and Pieters have not been behind when they've played as a pair.
Rory McIlroy with a birdie on the second. A fine effort from around 25 feet. Can Johnson or Koepka follow it up?
To match one where all four players fail to make a birdie on the first. Rory McIlroy vs Dustin Johnson in that one remember; two of the best players - if not the best - in the world right now. All square in that top group.
And we're back live from Hazeltine. The afternoon fourballs are already underway, though there will be a delay to the final two matches after the late finishes to the foursomes. It's been a stunning afternoon and something tells me there is more to come.
Reed keeps his nerve and United States have at least a half. Garcia will putt for the half, which will feel like a whole point. He makes it, and we're at 6 1/2-5 1/2 going into the fourballs.
No rest for the wicked and just as the final group leave the 18th, we're back to the first for the start of the fourballs. We're going to take a small break and come back for shot-by-shot coverage of the afternoon session. It has been a thrilling afternoon, so don't move a muscle.
Europe on the green and Cabrera Bello to putt first, with America in the rough and facing a downhill chip. The Spaniard nestles up to the hole and that should be a four. Now to Spieth, what can he do from around 12 feet, but in some deepish rough. This to win the match, but surely the half will be in his mind. He shoots past and that gives Reed seven feet to secure the half point.
Fourball pairings have been announced. We kick-off at 12:30pm, 6:30pm UK time.
So, we go to 18 in match four where the United States led by four around 75 minutes ago. Cabrera Bello finds the middle of the fairway, while Spieth goes way to the right. If Europe can steal a halve from this, it would be a huge psychological blow to strike ahead of the fourballs.
Spieth cannot believe the ball hasn't dropped at 17, shaving the edge of the hole, and he'll be in complete disbelief now as Cabrera Bello chips from off the green to draw the final match all square. They go down the 18th all square having trailed by four after 12 holes.
Europe close the gap again as Chris Wood cosies up to the hole to defeat Walker and Johnson. A first point for the Englishman.
Snedeker and Koepka put the USA back on course in the foursomes.

Now Rose finds the green and surely that will be enough, unless Walker finds the hole from off the rough, to secure the point.
Zach Johnson with a pivotal approach at the 18th. A halve for the USA here would be a real steal but he goes through the back and is up against the grand stand.
A putt to win the match for Chris Wood at the 17th. USA virtually have their par via Walker's effort. The English has about 20-feet for his first Ryder Cup point. He leaves it two feet short.
Johnson makes the five-footer which keeps the United States in the match. They go down the 18th. What a half that would be for the hosts.
Reed and Spieth have reeled off three straight bogeys and suddenly their lead is only two going down 16, where there is more water. Hope still for Garcia and Cabrera Bello.
Jordan Spieth in the water too at the 15th and Garcia and Cabrera Bello look like to get another shot back.
On to the 16th where Rose has a putt for a par and to make the USA putt for the hole. The Olympic champion holds his nerve and is that enough for the halve? Zach Johnson is a master from this range and he cut the lead to one. We're going all the way here, it seems.
Two matches left on the course but Justin Rose finds the water and the European lead looks like being cut. Jimmy Walker finds the green and is inside six feet. From three up with five to play, this has fallen apart for Europe.
A point for the United States in match two as Fitzpatrick misses a putt to keep the match alive. Victory over 3&2 for Snedeker and Koepka.

Fitzpatrick and Stenson have unravelled and the ball is in the water. Koepka's second shot did drift back towards the water but he gets held up on the bank.
Chris Wood lips out as Europe's lead in match three is reduced to two with four holes to play. Sergio Garcia gives him and Cabrera Bello hope with a par putt to go just three behind Spieth and Reed. Are the American's running out of steam?
Europe win the top match 4&2 to reduce the deficit further on the United States. Fowler misses a par putt on 16 as that match concludes.
But there is more for the Hazeltine crowd to cheer as Jimmy Walker holes from 20 feet. Europe still have a birdie putt coming up.
And the pressure is too much for the Englishman. Fitzpatrick misses to the left and the US go two-up in the second match. Huge moment.
Europe have two putts to win the top match after Mickelson goes past the pin at 16. McIlroy will putt for eagle. At 15 meanwhile, the US have a third straight birdie via Koepka. Fitzpatrick putting for a halve.
Stenso with a golden approach at the 15th, just when Europe needed it. Is that the opening he and Fitzpatrick need? Koepka and Snedeker have gone birdie-birdie from the last two and they'll need that again to stay ahead.
Rose and Wood now lead by three as Koepka's putt misses at the 13th. Two points looking in the bag for Europe, and with match four slipping away from them it is all about match two.
Pieters with a putt to win the hole and leave Europe dormie three in the top match. And he makes it! It turns to the right and he and McIlroy go mad on the 15th green. More fist pumping from the European team.
Matthew Fitzpatrick welcome to the Ryder Cup. A fabulous approach to go within two feet. That's a gimmie for Europe and they should draw level in that match.
Mickelson playing out of the leaves on the 15th. He misses the green and is on the downslope towards the water, but avoids getting his ball wet.
Zach Johnson with a very important half at the 12th as Europe remain two up. Match two at this stage looks absolutely crucial for both teams.

The American fans are out in force again at Hazeltine.
Jordan Spieth misses from eight feet; remember where you were and him and Reed stay three ahead in the bottom match.
Big chance for Fitzpatrick on 12 but he doesn't get the break and it allows the US the chance to edge ahead again in the second match. Koepka has one down hill, right to left but he goes four feet past, and that won't be conceded.
Patrick Reed has played a blinder this week and he goes within five feet at the 10th. There are shades of Ian Poulter about the Texan, who has come alive again during a Ryder Cup week.
Henrik Stenson goes way right off the tee. Not an ideal way to open up on 12, with water now between him and the green. Rickie Fowler also in trouble in match one off the tee at 13, which is only a par three.
We're back to all square in match two for the first time since the opening tee shot was struck, as Snedeker misses his first putt of what seems like the whole week. Chris Wood meanwhile converts the beautiful Rose approach to put Europe 2UP in match three. Suddenly blue dominates the scoreboard.

It's a chipping contest at the 11th. Fowler hit a low one and it goes past the pin. Pieters sees that and holds back, pulling his short. Tough putts for Mickelson and McIlroy there.

McIlroy's errant drive is punished by Mickelson, who finds a birdie to win a second hole in a row. Europe's lead reduced to one and the match is back in the balance.

Europe pull one shot back in the second match as Fitzpatrick makes birdie at the 7th. Shots to be made all over this course this afternoon.
Reed chips in brilliantly off the green and USA are close to going three-up in the bottom match. But no! Garcia makes birdie himself and Europe get the halve.
Phil Mickelson with some brilliance at the 8th, a birdie from fully 25 feet. Europe had looked odds on to win it, but that is a timely intervention from 'leftie'.
A rather curious occurrence at the fifth, where Rafa Cabrera Bello's drive has landed in the pocket of a marshall on he course where the match referee has been enlisted to sort out the situation.
Birdie chance for Matthew Fitzpatrick and it's a mighty fine effort from him to go within less than a foot. Koepka can win the hole from a sightly shorter range, but his effort dives to the left.
Pieters keeps Europe 3UP with a fine five. The Belgian pumps his fists, McIlroy geers up the crowd and America will be deflated by that.
Garcia and Reed see their putts go by to the right of the hole in remarkably similar fashion, and that 4th is halved.
Fowler with a chance to reduce the arrears in match one after Europe found the water off the tee. But he can't take advantage and Pieters can make amends for his errant drive.
Europe might be two down in the bottom match but they're played very well. Spieth and Reed have reeled off three straight birdies and are already 2UP to the good. Spieth plays a delightful tee shot to within 20 feet; matched by Cabrera Bello with both balls side by side.
Thomas Pieters finds the creak on the seventh. And it's further bad news for Europe, as first Cabrera Bello lips out, and then Spieth finds the middle of the cup from 10 feet.
Hazeltine looks an absolute picture this morning.
Rickie Fowler with a putt for birdie and he has the line, but not the pace. Pieters can't take advantage however as he goes left. Fitzpatrick makes a decent par at the fifth meanwhile.
Europe are on the green within 20 feet in the top match at the sixth. Mickelson has an awkward pitch from the edge of the bunker and he puts it on the putting surface. Both should two putt from there.
Chris Wood helps Europe make birdie at the par five 3rd, but Jimmy Walker matches it from six feet. That third match is all-square.
Two missed European putts sees USA take control of two matches on course. Stenson is the first as his birdie lips out again, to allow Snedeker and Koepka to go 2UP. Then Cabrera Bello misses, giving Spieth the chance to put USA 1UP in the bottom match.
Can Mickelson drag USA out of another hole? No as he misses to the left and Europe go three up through five. Ridiculously one-sided one-sided contest.
McIlroy chips beautifully to within seven feet and Europe have the chance to go 3UP after five holes. Fowler faced with a slippery chip and as it prove as he rolls to the edge of the green, around 20 feet past.
Mickelson having to play right-handed up against the fence. Some skill required he to hook this back into play. The ball bounces across the green and back into the rough. The American's have been all over the place this morning in this top match.
Stenson can draw the second match all-square with a birdie from around 20 feet. He comes up just a little short, so the hole is halved.
Spieth's approach is nullified by Garcia, who makes birdie from 10 feet. Crucial put with Reed so close, a putt he doesn't miss.
Fowler inaccurate off the tee again, going way right from the 5th. Mickelson in trouble again.
Stunning from Jordan Spieth. Perfect drive from Reed and it's converted by the two-time major champion who goes within five feet. Birdie incoming on the first for the Americans.
Europe go 2UP in the top match with Pieters making another putt. Fowler and Mickelson falling apart again.
Sergio Garcia goes a little left but he's only in the first cut of rough, just off the fairway. Decent line from there. There is a BBQ engulfing much of the first tee but Patrick Reed is unperturbed and he finds the right-hand side of the fairway.
Garcia and Cabrera Bello arm in arm on the first tee. Such a physical embrace is not the style of Reed and Spieth and they look ready for action after an up and down first day. Can the Spaniard's repeat their afternoon heroics from day one?
Fitzpatrick keeps his nerve and USA remain just one up after two in match two. In match three meanwhile, Justin Rose chips to within a foot and the putt in conceded.
Snedeker couldn't make his putt from 15 feet, and now Europe are in trouble as Stenson goes five feet past for his birdie. Work for Fitzpatrick to do.
Fowler with a putt to halve the third. His approach put the USA in trouble in this hole but he drags them back into contention with fine hold.
Chris Wood plays his first shot in Ryder Cup history and it's a nice little chip to the back of the green at the 1st.
McIlroy misses a chance to win the hole but American still have a tough one to make their par at the 3rd.
Jimmy Walker has to be the poor rest ball striker in the American team and he's found the front of the green from the bunker at the 1st.
Rickie Fowler has put Mickelson in trouble at the 3rd, where the ball is lying on the tee box at the fourth hole. Outstanding though from the five-time major winner, who is on the green.
Fiztpatrick puts it on a plate for Stenson at the second with a fine second shot. Snedeker is faced with matching that stroke but he's at least 20 feet back. Chance for Europe to draw that match level.
Now to match three where Chris Wood becomes the final player to take his bow at the Ryder Cup. Rose has the honour of the opening tee shot and finds the fairway, though Zach Johnson is in that right-hand side bunker.
And Stenson can't make the putt and USA go 1UP in match two.
Pieters and Fowler with two storming drives at the par five 3rd. Back to the first, and Fitzpatrick comes up short with his chip from the deep rough and American have a put to take the lead. Koepka comes up short, but he knows Stenson has 10 feet to make his par.
USA finally punished for their wayward iron play and McIlroy holes for a second straight birdie to put Europe 1UP.
The scene on the first tee as Thomas Pieters got the day underway.
Snedeker is in a horrid position on the 1st. He has a line of sight relief but there remains three huge oak trees in his way. A low scuttler is required here, but can he carry to the green? He somehow finds the gap and the green. It's a terrific recovery.
Rickie Fowler gives USA a birdie chance on the second, going to within 15 feet. Pieters only has to feather this from the fairway for Europe and he goes to within 12 feet. McIlroy and Mickelson with a putt-off for the hole.
Match number two preparing to get underway on the first tee. Snedeker and Koepka were the only scorers for USA in the fourballs and they will hope to repeat that today.
Fitzpatrick opens up for Europe on debut and he makes a fine start sending the ball down the right of the fairway, but avoiding the bunker. A huge sigh of relief for the Englishman. Koepka goes way left however and is up against a fence. He's get relief from there but it's a far from ideal start.
Wonderful exchange as Pieters holed that one. Mickelson and Fowler smiling and applauding, as Pieters put his finger to his lips towards the American crowd. Day two has taken just one hole to catch light.
The crowd at the first tee go mad and now it's left to Pieters to respond. Pressure on the rookie and he responds. Birdie-birdie start and it's all-square. Brilliant from the Belgian.
So two birdie chances at the first for USA and Europe. It's Fowler to putt first. It's an uphill, right to left one and it drops brilliantly. What a start for the United States! From the bunker it's a birdie start in match one.
So Mickelson from the sand and he's on a little bit of an upslope off the right. It's a fine effort from 'leftie' however, who finds the back left of the green. McIlroy could not be better placed, just 125 yards to the pin an it's a fine effort from him to within around 18 feet.
Darren Clarke labels today foursomes pairings as "options". Very coy from the European captain, who says he has full belief in Fitzpatrick and Wood to do the business in the more difficult discipline of foursomes.
The honour of the first tee shot goes to Thomas Pieters, and it's a belter which cuts the fairway in half and day two is officially underway. Rickie Fowler is next up for USA but he goes way right with his drive and finds the bunker. Advantage Europe, if you can call it that, after the opening tee shots.
So all of this morning's scheduled matches are at the top of the page and they will be updated as the session progresses. I shall be providing shot-by-shot updates over the next 10 hours or so live from Hazeltine, where I am currently one of only a handful inside what is a massive media centre.
Both captains are on the first tee already; Davis Love III of the United States and Europe's Darren Clarke. The Minnesota sun has peaked through for the start of day two and we're around five minutes away from starting. It's a picturesque site at the first.
Hazeltine ready for play to get underway.
All the talk this morning since the end of play yesterday has been of the final act of the day; Rory McIlroy's celebration. The Northern Irishman made a eagle three to close out the match and confirm Europe's third point of the day, but was his uncharacteristic celebration disrespectful? Here is what McIlroy had to say.
For me, even before I hit that putt, I wanted to put an exclamation point on that session for us. I honestly actually thought about the celebration before I hit the putt. I sort of knew . It's a hostile environment out there, and I just want everyone that's watching out there to know how much this means to us, how much it means to me personally and obviously us as a team.
Rory McIlroy on the range ahead of the start of his foursomes match against Phil Mickelson and Rickie Fowler. The four-time major winner has donned a European beanie for the morning session, a subject which has certainly drawn interest from the American media. Darren Clarke has been asked about his team wearing hats on two occasions now in what must be said is a bizarre line of questioning. He is the captain's response from yesterday:
We don't all wear hats. We don't all wear them all the time. Some guys wear them.
Some guys don't. You know, it's not -- the hats are there. I think there's maybe ten different choices of hats in the locker room and they had the choice if they want to, whichever one they want or if they don't want to wear any at all. Sometimes the guys just, they don't want to wear -- there's no particular reason for it.
More hat updates on the way from Hazeltine.
Darren Clarke resisted in fielding two of his rookies on day one, but they are being thrown into the spotlight this morning. Matthew Fitzpatrick will be paired with Henrik Stenson in match two, while Chris Wood joins Justin Rose in an all-English group in match three. Two seniors taking on the responsibility of shadowing two debutants there in what could be two key matches.
For those of you watching perhaps from the UK or elsewhere in Europe, if you're tuned in for any of the television coverage you'll likely have seen that at least in the morning Hazeltine is covered in darkness almost until just minutes before play is about to begin. I can tell you from walking around the course yesterday and early this morning that your television pictures do not do justice to the amount of light around. It is still very gloomy out there and yet we're only 30 minutes until the first tee time.
Welcome back to Minnesota where we are just over half an hour away from the resumption of the 41st Ryder Cup. United States produced their first opening session whitewash for 41 years on Friday, but they were pegged back by Europe to set up a tantalising second day at Hazeltine.
We'll have live coverage from Chaska throughout the day, starting with the morning foursomes and then into the evening fourballs as Team USA and Team Europe seek to take a lead into Sunday's singles matches. Until then we'll look back at day one and preview what should be another thrilling day in team golf's ultimate competition.
