Tennis

Rafael Nadal becomes No. 1 in the world today. He'll also wake up an Olympic champion.

Nadal overcame two set points in the second set and held every service game to beat Chile's Fernando Gonzalez 6-3, 7-6 (2), 6-3.

The Williams sisters (above) won the women's doubles title by romping past Spain's Anabel Medina Garrigues and Virginia Ruano Pascual 6-2, 6-0. They also won in Sydney.

"I'm so excited, I can't even speak," said Venus, who has already won seven doubles Grand Slams and a gold medal in Sydney alongside her sister. But, winning as a family never grows old. "To share this kind of moment with your sister," she said, gives her "chill bumps.

Track and field

China's Liu Xiang, the reigning Olympic 110-meter hurdles champion, is as popular in China as Yao Ming. But he has been battling hamstring and foot problems, and he limped into the starting block for his first heat Monday morning. He burst out at the gun, then pulled up lame after a few steps.

Shooting

After blowing gold by shooting at the wrong target four years ago, American Matt Emmons was back in the lead on the last shot of the same event. He was determined not to make the same mistake again. He didn't — he made a different one.

Emmons' gun fired before he was ready. Instead of the measly 6.7 he needed, he got an atrocious 4.4, dropping him to the cruelest spot of all, fourth. At least last time he got silver.

Beach volleyball

There won't be an all-American women's finals.

Elaine Youngs and Nicole Branagh were ousted with a loss to a Chinese team. Earlier Sunday, Americans Kerri Walsh and Misty May-Treanor advanced to the final four with a straight-sets victory over Brazilians Ana Paula and Larissa.
