Rio 2016 medal count: Usain Bolt wins Jamaica’s 2nd gold, Great Britain wins 8 medals Sunday

Usain Bolt is the fastest man alive, and no one’s coming close. With one of his patented second-half surges, Bolt overcame the field and took the gold medal in the 100-meter race with a time of 9.81 to retain his title and become the first man to win three consecutive golds in the event.

His win in the 100 meters gave Jamaica two golds in Rio and three medals total. The big winner on Sunday was Great Britain, which added five golds and three silver medals to its coffers for the 2016 Summer Olympics, bringing its total in Rio to 38 medals — 15 gold, 16 silver and seven bronze.

In men’s tennis singles, Andy Murray won his gold medal match against Argentina’s Juan Martín del Potro in four grueling sets. Murray retained his title after winning the gold medal in tennis singles at the 2012 London Olympics.

Britain’s Justin Rose won the golfing gold medal with a four-under 67 that was the first gold medal handed out in since 1904. Golf was reinstituted as an event at the Rio Olympics for the first time in more than a century.

Great Britain is second only to the United States in both gold and silver medals. The Americans lead with 69 total medals through Sunday — 26 gold, 21 silver and 22 bronze.

Bolt is undefeated in global competitions he has actually run in since the 2008 Beijing Olympics. On Sunday, Jamaica’s track star started slow before blowing past the field in the final 40 meters of the race, including silver medalist Justin Gatlin of the United States and Canada’s Andre De Grasse of Canada with bronze.

Wayde van Niekerk didn’t just set the world record while winning a gold medal in the 400-meter on Sunday -- he demolished it. The South African runner, trained by a great-grandmother, easily took first place during the race with a time of 43.03 seconds, topping Michael Johnson’s prior world record of 43.18 seconds and his Olympics record of 43.49 seconds.

Simone Biles won her third gold medal at Rio by dominating the vault. Her average of 15.966 wasn’t even close to the silver medalist, Russia’s Maria Paseka with an average of 15.253.
