Track and field dominated the Olympic headlines today, as the semifinal and final heats of several races took place. Tennis also had a big day, as a pair of Americans took home the gold. Here’s a recap of today’s events. 

Tennis

Two of America’s most recognizable female tennis stars, Venus and Serena Williams, took home the gold today in the women’s doubles final. They defeated Andrea Hlavackova and Lucie Hradecka of the Czech Republic in straight sets in a thoroughly impressive performance. The match capped off a brilliant weekend for Serena Williams, who took gold yesterday in the women’s singles final against Maria Sharapova.

The men also played this morning, with Roger Federer facing Andy Murray for the gold. Despite Federer coming in a heavy favorite, Murray pulled the upset in dominant fashion, winning three straight sets (6-2, 6-1 and 6-4). The victory was even more sentimental for Murray, given that it came in his home nation. Even with past disappointments in tournaments, this victory was “…the best way to come back from the Wimbledon final,” he said.

Track and Field

The excitement continued in the track and field events on Sunday after a thrilling start.

Superstar sprinter Usain Bolt took to the track in perhaps the most highly-anticipated event of the Olympics — the men’s 100-meter dash. While he was expected to defend his 2008 gold medal, Bolt had been pushed throughout the year by competitor and fellow Jamaican teammate Yohan Blake.

As usual, he blew everyone out of the water with his performance.

Bolt won gold again and set a new Olympic record with a time of 9.63 seconds in London. He was just .05 off from his 2009 world record of 9.58. Blake won silver with a time of 9.75 and American Justin Gatlin took the bronze with a 9.79.

South Africa’s Oscar Pistorius failed to qualify for the 400-meter final in today’s heat. The Paralympic champion, who has two carbon-fiber blades for legs, finished last in his heat with a time of 46.54. Pistorius had become one of the biggest stories of the Olympics due to his disability.

Americans Sanya Richards-Ross and Deedee Trotter took gold and bronze in the Women’s 400 meters today. Richards-Ross came in with a time of 49.55, while Trotter finished in 49.72.

Women’s Basketball

The American women’s basketball team defeated China in a rout on Sunday with a final score of 114-66. The 114 points tied the team’s scoring record in an Olympic game. The game was the team’s 38th-consecutive victory in Olympic play, and Americans haven’t lost a preliminary round game since 1976.

The remaining matchups of the women’s tournament are France against the Czech Republic, Australia against China and Russia against Turkey. 

Trojans in the Olympics

Jesse Williams tied for third during high jump qualifying. He will compete in the final on Tuesday.

Jennifer Kessy and April Ross defeated Kristyna Kolocova and Marketa Slukova of the Czech Republic. They will play in the semifinals on Tuesday against Brazil's Larissa Franca and Juliana Silva.

Trojan runner Bryshon Nellum fell short of qualifying for the 400-meter final today, missing out by just 0.03 seconds. Nellum, who was shot in the thigh during his freshman year at USC, recovered all the way to compete at the Olympics. He still has another medal opportunity with the  4x400 relay team.

Zsofia Erdelyi (Hungary) and Tina Kefalas (Greece) placed 92nd and 104th, respectively, in the marathon.

Nicole Davis played in Team USA's win over Turkey in women's volleyball in straight sets (27-25; 25-16; 25-19). It plays the Dominican Republic on Tuesday in the quarterfinals.

Lauren Wenger had an assist in a 9-6 Team USA's victory over Italy in the women's water polo quaterfinal. Fellow Team USA Trojans Kami Craig and Tumua Anae did not compile any stats. Italy's Aniko Pelle played but failed to score. Team USA plays Australia on TUesday.

Flora Bolonyai had an assist in a tight victory for Hungary over Russia, 11-10. Russia's Sofia Konoukh had one shot. Hungary plays Spain on Tuesday.

Spain's Anni Espar racked up two goals and two assists as they bested Great Britain 9-7.
