Rio 2016 day 12: GB hockey women reach final as Bolt storms into 200m final

Team GB did not manage to add to an impressive haul of 50 Olympic medals on day 12 of their best overseas Games at Rio 2016, but the women's hockey team continued the feel-good factor by guaranteeing themselves at least a silver and reaching their maiden final with a 3-0 win over New Zealand.

Danny Kerry's side, bronze medallists at London 2012, will meet the defending champion Netherlands in Friday's showpiece after a brace from Alex Danson and Helen Richardson-Walsh's penalty stroke ensured a comfortable if occasionally brutal victory over the Black Sticks. The Dutch team sealed their progress via a sudden death penalty shoot-out defeat of Germany.

Great Britain were expected to add a 20th gold to their tally on Wednesday afternoon, only for the sailing regatta to be delayed and eventually postponed due to a "lack of breeze and an unfavourable wind direction". Women's 470 pair Hannah Mills and Saskia Clark boast an unassailable 20-point lead over New Zealand duo Jo Aleh and Olivia Powrie in the overall standings and only have to finish the rescheduled medal race in order to seal victory.

In the boxing, Hartlepool's Savannah Marshall suffered more Olympic heartbreak after losing her 75kg middleweight quarter-final bout against Nouchka Fontijn of the Netherlands. Badminton singles hopeful Rajiv Ouseph, meanwhile, lost his last-eight tie against Denmark's Viktor Axelsen in straight sets and Liam Phillips finished 10th fastest in the BMX time-trial run that determined seedings for the quarter-finals.

Diver Tonia Couch qualified fifth for the women's 10m platform semis with a score of 332.80, but teammate Sarah Barrow was eliminated after placing 23rd. Liam Heath and Jon Schofield reached the final of the men's kayak double 200m, although there was disappointment for Rachel Cawthorn in the women's single 500m. Brazil's men's football team took another huge step towards a maiden Olympic gold after Neymar notched twice during a ruthless 6-0 rout of Honduras at the Maracana Stadium. Germany will provide their final opposition following a 2-0 win over Nigeria.

At a hot and humid Estadio Olimpico, Mo Farah survived another near fall in the morning session to reach the final of the 5,000m and keep his 'double-double' dream very much alive. Lynsey Sharp won her 800m heat to qualify for the semi-finals, as did controversial favourite Caster Semenya. Shelayna Oskan-Clarke's third-place finish was also enough to progress. GB will have no representative in the deciding stage of the men's hammer throw event after Chris Bennett, Mark Dry and Nick Miller were all knocked out along with Poland's Pawel Fajdek.

Conseslus Kipruto of Kenya set a new Olympic record en route to winning gold in the men's 3,000m steeplechase ahead of American Evan Jager and Mahiedine Mekhissi-Benabbad, the latter of whom was promoted to bronze after the disqualification of experienced two-time champion Ezekiel Kemboi.

The evening athletics slate was headlined by Jamaica's Elaine Thompson, who beat world champion Dafne Schippers and Tori Bowie in the women's 200m final to become the first female athlete to secure an Olympic sprint double since Florence Griffith Joyner at Seoul 1988. Britain's fastest woman, 20-year-old Dina Asher-Smith, came fifth.

Controversial sprinter Justin Gatlin's failure to reach the final of the men's event rightly registered as a significant shock. Yohan Blake also missed out, but Usain Bolt, along with fastest loser Adam Gemili, progressed after a comical battle with Andre De Grasse at the finish line. Danny Talbot did not make it through despite running a personal best of 20.25, while Nethaneel Mitchell-Blake also bowed out.

Cindy Ofili came within 0.02 seconds of a bronze medal in the women's 100m hurdles, but was narrowly edged into dreaded fourth place by Kristi Castlin. Sister Tiffany Porter was seventh. New world-record holder Kendra Harrison remarkably did not even qualify for Rio, but that did not stop Team USA sealing a dominant 1-2-3 led by Brianna Rollins and Nia Ali. In the long jump, Tianna Bartoletta leaped 7.17m to take the title from compatriot Brittney Reese. Ivana Spanovic was third, while British hopefuls Jazmin Sawyers and Lorraine Ugen finished eighth and 11th respectively.

World and defending Olympic champion Ashton Eaton leads the decathlon after day one with a total of 4621 points. The American won both the long jump and his 400m heat in addition to finishing as runner-up to Damian Warner in the 100m. The final five events take place today.
