Athens, Greece ? Michael Phelps won his second and third gold medals of the Athens Games, winning the 200-meter butterfly and then helping the United States win gold in the 800 freestyle relay Tuesday night.

Phelps held off Takashi Yamamoto of Japan in the butterfly to win in an Olympic-record 1 minute, 54.01 seconds. In the relay, Klete Keller narrowly held off Ian Thorpe at the wall to help the U.S. win gold over the Australians four years after finishing second to the Aussies at the Sydney Games.

The Americans picked up another medal when Amanda Beard took silver in the 200 individual medley.

Women’s Soccer

Joanne Peters’ 12-yard header in the 82nd minute gave Australia a 1-all tie with the United States. The Americans already had clinched a spot in the quarterfinals with wins over Greece and Brazil, and the tie assured them first place in their group. Their top seed guarantees they will stay in Thessaloniki for their next game against Japan on Friday.

Men’s Soccer

Mexico beat Greece, 3-2, only to discover it still had been knocked out of the competition. After celebrating a victory over the host, the Mexicans heard the other group game had finished in a tie between Mali and South Korea — eliminating them.

Softball

Lori Harrigan allowed only a first-inning bunt single, and Crystl Bustos homered Tuesday as the United States posted its fourth straight shutout of the games, 4-0 over China. Harrigan struck out eight, Lovieanne Jung had two RBIs, and Leah O’Brien-Amico drove in a run as the Americans ran their winning streak to 74 games.

Fencing

For the first time in a century, the United States won a gold medal in Olympic fencing, and it added a bronze for good measure. Mariel Zagunis beat Tan Xue of China, 15-9, in the saber final, and American Sada Jacobson was third, beating Catalina Gheorghitoaia of Romania, 15-7.

Tennis

The world’s top two tennis players found themselves struggling against low-ranked opponents in the second round of the Olympics — No. 1 Roger Federer flopped, and No. 2 Andy Roddick flourished. Federer was beaten, 4-6, 7-5, 7-5, by 18-year-old Tomas Berdych of the Czech Republic on Court 1. Roddick saved three match points and overcame 2000 silver medalist Tommy Haas of Germany, 6-4, 3-6, 9-7, before a raucous crowd at the main stadium.

Venus Williams beat Maja Matevzic of Slovenia, 6-0, 6-0, earlier — the first shutout for a man or woman since tennis returned to the Olympics as a medal sport in 1988.

Baseball

Daisuke Matsuzaka shut out Cuba for eight innings, leading Japan to an impressive 7-3 victory over Cuba. The round-robin win was a breakthrough for Japan, which sat on the sideline while Cuba and the United States won the first three golds in Olympic play. Matsuzaka allowed only four hits.

Volleyball

The U.S. men bounced back from their opening loss with a straight-sets (26-24, 25-20, 25-18) victory over the Netherlands. Opposite Clay Stanley led an all-around effort with 21 points, and the Americans ended a nine-match Olympic losing streak with very few errors, strong defense and excellent serving.

Boxing

Ron Siler opened his quest for a gold medal with a convincing 32-18 decision over Australia’s Bradley Hore in a first-round flyweight fight. The win kept American boxers undefeated in the Olympics.
