Highlights

DIVING

Becky Ruehl starred and Mary Ellen Clark barely survived qualifying in a surprising opening day on the 10-meter platform.

WATER POLO

Chris Humbert’s temper got the best of him again and it was the worst possible thing for the U.S. team, which then lost all medal hope.

TABLE TENNIS

Top American Amy Feng, once China’s third-best singles player, won the first set but lost to former countrywoman Liu Wei.

BOXING

Americans apparently lose and learn as three fighters perform smartly while earning spots in their respective quarterfinals.
