IT BEGINS FOR PHELPS, HOFF: Swimming is one of two sports NBC insisted on having in prime time for U.S. audiences. The other was gymnastics. Michael Phelps of Rodgers Forge goes for gold medal No.1 tonight in the 400-meter individual medley between 10 and 11p.m. It might be the most challenging of the eight races he plans to swim because of anticipated competition from U.S. teammate Ryan Lochte. Katie Hoff of Towson also swims the 400 IM tonight and faces a challenge from Australia's Stephanie Rice. Hoff is seeking her first Olympic medal. Chs. 11, 4
THE REAL DREAM TEAM: Going for a fourth consecutive gold medal, the U.S. women's basketball team opens against the Czech Republic. While Lisa Leslie is still around, one of the rising young stars in the pro game, Candace Parker, leads the Americans. 8 a.m., USA Network
ROGER VS. RAFAEL?: Tennis' fifth Grand Slam opens with the first round of men's singles. Roger Federer vs. Rafael Nadal in the final, anyone? They play here on hard courts, which would have been considered an edge for Federer. But after Nadal won on grass at Wimbledon, it's anyone's guess. CNBC
