LeBron James and Team USA take on Argentina in the men's basketball semifinals.
Here's the Fab Five for Aug. 10, which will highlight NBC's prime-time schedule starting at 8 pm Eastern:
1. Women's 4x100m Finals
Allyson Felix and Carmelita Jeter will try to lead the U.S. to the medal stand and past those pesky, dominant sprinters from Jamaica. The U.S. women posted the second-fastest time in history in the semis, so they have to be considered a slight favorite in what will be a start-studded event.
2. Men's 4x400m Finals
I don't know about you, but the guy I'm rooting for won't even be running today. American Manteo Mitchell helped the U.S. team make it through the preliminaries despite suffering a broke fibula midway through his leg of the race. After letting out an audible scream, Mitchell gutted out a respectable 46.1 lap as the Americans tied for first in the heat. Mitchell will be watching the finals but will still get whatever medal his teammates earn. The team from the Bahamas looks like a medal threat as well.
3. Basketball Semifinals: Team USA vs. Argentina
Things are getting real for Team USA as they face a talented, determined Argentine team in the semifinals. There's lingering bitterness over Argentina's win against the Americans in the semifinals in Athens in 2004, and the Argentines ramped up the intensity with some dirty play in the two teams' previous encounter in these Games, won by the U.S. 126-97.
4. BMX Cycling
The men's and women's finals in this thrilling niche sport are both on Friday. Dutch rider Raymon van der Biezen has become the story of this event, battling a series of injuries to lead his team into gold medal contention.
5. Men's 10m Platform Diving
The remarkable elegance of the Chinese divers will again be on display as China's Qui Bo is one of the favorites for gold. Britain's Tom Daley and American David Boudia are also medal contenders, as is defending gold medalist Matthew Mitcham of Australia.
