Wimbledon 2016: Novak Djokovic shocked by big-serving Sam Querrey at SW19

Defending champion Novak Djokovic is out of Wimbledon after being being defeated in four sets by Sam Querrey at SW19, to end his 30-match unbeaten run in grand slams. The world number one had no answer to the big-serving American during a match spanning two days due to four separate rain delays.

Djokovic trailed by two sets overnight but won the opening four games prior to the first break for rain, before taking the opening set on the resumption. The three-time champion at the All-England Club saw 11 consecutive break point chances come and go in the decisive fourth set, before claiming a break to go 5-4 in front.

Querrey, who had lost in the first round of his last three major appearances, was unruffled by the onslaught and broke Djokovic to level the match, and then forced the 12-time grand slam champion to serve to stay in the championship. Another delay of over an hour followed, but Djokovic held his nerve to take the set to a tiebreak.

The number one seed held the upper-hand with an early mini break, which he held until Querrey won five of the next six points to set up two match points. Djokovic saw off the first on his serve with an ace but an engrossing rally followed which saw a forehand sent long to confirm a 7-6 6-1 3-6 7-6 loss and the upset of the tournament so far.

While Querrey will face Frenchman Nicolas Mahout in the fourth round, Djokovic is left to consider a first grand slam defeat since the 2015 French Open and a first major third round exit for seven years, amid questions over his temperament both during the opening two sets of the match and his practise session on day six.

"It's incredible, especially to do it here at Wimbledon," the 28-year-old said Querrey. "I am so ecstatic right now and so happy. That is about it. I think today I played the break points really well. When I had a break point I was able to come up with a big served then I fought in the tight breaker, had a few loose errors and that was it.

"He came out and got the first four games and fortunately we had another rain delay so I got to regroup. He's on his way to being one of the best ever, you know he's so mentally tough and he was going to come back. I am just taking it one round at a time, I don't even know who I am playing next. I'm just going to be happy with this and look forward to the next round a little bit."
