What To Watch on Day 13 of the Summer Olympics, beginning with women's volleyball and ending with two of the Games' must-see events: USWNT in the gold medal final and Usain Bolt running for Olympic history.
Day 13 of the 2012 Summer Olympics should be one of the most exciting days yet, featuring two of Games' most highly anticipated events.
The day begins with the U.S. women looking to advance to the gold medal match in volleyball, and is followed by Claressa Shields fighting in the women's middleweight finals, looking to bring home America's only boxing gold medal.
And then, at 2:45 p.m. ET, in one of the must-see events -- not just on Thursday but for the entire Olympics -- the U.S. Women's National Team goes for soccer gold -- and revenge -- against a Japan squad that beat them in heartbreaking fashion at last year's World Cup.
The day ends with can't-miss competition on the track, as Usain Bolt runs for more Olympic gold in the 200m, and American Ashton Eaton completes his quest to win men's decathlon.
What To Watch on Thursday, Aug. 9, at the Summer Olympics:
Women's Volleyball Semifinals, United States vs. Korea, 10 a.m. ET, NBC
Can the U.S. women do what their male counterparts couldn't -- and what their beach counterparts both accomplished -- and advance to the gold medal match? The Americans, the No. 1 ranked team in the world, are looking to improve on their silver from Beijing.
Women's Boxing, Middle (75kg) Gold Medal Bout, 12:15 p.m. ET, CNBC
Claressa Shields, just 17 years old, is the United States' only chance at a boxing medal in London.
Women's Soccer Gold Medal Match, United States vs. Japan, 2:45 p.m. ET, NBC Sports Network
The must-watch event of Thursday. The U.S. Women's National Team, No. 1 in the latest FIFA rankings, is going for its third-straight gold, and fourth in the five Sumer Games women's soccer has been included. Standing in their way is Japan (No. 3), the squad that beat the Americans in the 2011 World Cup final a bit more than a year ago, winning in penalties.
Women's Water Polo Gold Medal Match, United States vs. Spain, 3 p.m. ET, NBC
After silver in 2000 (women's water polo's Olympic debut), bronze in 2004 and another silver in 2008, the United States will be looking for its first ever gold in the event when it takes on a surprising group from Spain in the pool Thursday night. The two teams tied, 9-9, when they met in the preliminary round.
Track and Field -- Men's 200m Finals -- 3:55 p.m. ET (online); 8.p.m. NBC
Once again, the world's eyes will be focused on the track at London's Olympic Stadium as Usain Bolt runs for history -- no one has ever won gold in both the 100m and 200m in back-to-back Olympics. And while technically nine men are competing, including American Wallace Spearmon, this is a two-man race, with Bolt being chased by fellow Jamaican Yohan Blake, who beat the world-record holder at their country's Olympic trials.
Decathlon, 8 p.m. ET, NBC (live online throughout the day)
The 1500 meter run (4:20 p.m. ET) is the final event in men's decathlon, a 10-event, two-day competition that determines the title of "World's Greatest Athlete." After the first day, American Ashton Eaton, the world-record holder, was leading, followed by teammate Trey Hardee. If Eaton can hang on, he'll become the second-straight American to win gold (Bryan Clay won in Beijing), and will add his name to a list that includes Olympic greats like Jim Thorpe, Bruce Jenner and Dan O'Brien.
