Day 1 of the Beijing Olympics

Top three

Mariel Zagunis led a U.S. sweep of the women's saber fencing for the first American medals of the Beijing Games. Zagunis, the 2004 Olympic champion, beat Sada Jacobson 15-8 for the gold medal. Becca Ward took the bronze. The U.S. is the only country with three medals.

Medal count

China also started strong, winning two gold medals on the first day. Chen Xiexia won the first gold for the hosts, setting Olympic weightlifting records in the clean and jerk. Then, Pang Wei won the gold in men's 10-meter air pistol.

Katerina Emmons of the Czech Republic won the Games' first gold, in 10-meter air rifle. She's the wife of American shooter Matt Emmons and lives in the United States — but no, the medal doesn't count in the U.S. total.

Peking lame duck

President Bush tried his hand at beach volleyball, bumping passes to U.S. Olympian Misty May-Treanor and Kerri Walsh but deciding not to dive in the sand after a May-Treanor return. Said Walsh: "I think if he'd take his shoes off, he'd be a stud."

Quotable

"I wasn't fully prepared for the pressure of competing at home." — Du Li of China, the reigning gold medalist in the 10-meter air rifle, who lost to Emmons.
