Olympics Schedule: U.S. Soccer, Tennis Semifinals, Track & Field Among Aug. 3 Events To Watch

As swimming prepares to cede the Olympics spotlight to track & field at the London Olympics, the schedule is jam-packed full of compelling events. Here are five to look out for on Friday, August 3rd.

Beach Volleyball: The Round of 16 begins on Friday and the top-seeded Brazil women's team of Juliana Silva/Larissa Franca faces off against the Netherlands duo. USA's Kerri Walsh and Misty May aren't in action until Saturday, but the American team on the other side of the bracket -- April Ross and Jennifer Kessy -- takes on Switzerland. Todd Rogers and Phil Dalhausser will dive around the sand in some late night action as well.

Tennis Semis: If you want to catch a glimpse of Djokovic and Federer, you're going to have to get up early. And it will be worth it. The Serbian star takes on 2012 Wimbledon runner up Andy Murray, while the 17-time major champ goes up against Juan Martin del Potro at 7 a.m. ET. The 6'6 Argentine has given Federer plenty of trouble in the past.

Track and Field: Track and field finally gets started on Friday and the highly-anticipated showdown between America and Jamaica will begin with the women's 100-meter heats at 2:05 p.m. ET (preliminaries at 5:40 a.m.). There will be some medals handed out as well, including the Men's Shot Put and Women's 10,000m Final.

U.S. Women's Soccer: It's win or go home now. The quarterfinals of the women's soccer tournament kicks off Friday morning with dark horses Sweden and France squaring off against each other. And after that at 9:30 a.m., Abby Wambach leads the U.S. team against New Zealand. The U.S. went undefeated in the group stage outscoring its opponents 8-2, while New Zealand went 1-2 and gave up as many goals as they scored (3).

Phelps' Last Race: Michael Phelps may very well swim in his last Olympic race ever. It's been an incredible ride. 20 medals, 16 of them gold and one more race to go: The 100m Butterfly Final at 2:38 p.m. ET. Who knows if Phelps will be in the pool at the 2016 Games. This may be our last chance to see the most decorated Olympian of all time reign as king of the pool.
