Roger Federer is going home with a gold medal. Federer and Stanislas Wawrinka took the men's doubles title.

Federer and Wawrinka beat Sweden's Simon Aspelin and Thomas Johansson 6-3, 6-4, 6-7 (4), 6-3. Federer closed it out with a service winner, threw up his arms and began hopping, then hugged his partner. This should help salve finally losing his No. 1 status to Rafael Nadal on Monday.

Russia will win women's singles with countrymates Dinara Safina and Elena Dementieva squaring off. Dementieva beat another Russian, Vera Zvonareva, and Safina knocked out China's Li Na.

American twins Bob and Mike Bryan, who have won all four Grand Slam championships, won the bronze in men's doubles.

Novak Djokovic beat American James Blake for bronze in men's singles.

Track and field

Bolt got out of the blocks slow and crossed the line strutting. That tells you how good he was in between.

Before the finish line, the 6-foot-5 champion had his long arms spread, palms up, and pounded his chest. His left shoelace was even untied.

The clock initially showed 9.68, then was changed while reggae music blared and Bolt's party continued around the track.

Bolt broke the mark he set in May by .03. Richard Thompson of Trinidad and Tobago was second by 0.2 -- unlike the pool, this constituted more than a body length -- and American Walter Dix was third.

U.S. record-holder Tyson Gay didn't make it out of the semifinals. Asafa Powell, who held the world record for three years until Bolt came along, was fifth for the second straight Olympics.

Leila Ben-Youssef, of Sidney, Mont., had a somewhat disappointing showing in the pole vault preliminaries at the Olympic games.

Ben-Youssef tied for 32nd Saturday after clearing 13 feet, 1.5 inches -- a full foot lower than her qualifying height, reached at a meet in California in June.

The top 12 advanced to the finals.

The 26-year-old Ben-Youssef was one of only two track and field athletes representing her father's native country, Tunisia.

She won three state high school pole vault titles at Sidney High and also competed in pole vault at Stanford.

Swimming

Also at the Water Cube, 41-year-old Dara Torres came oh-so-close to capturing a gold medal in the 50-meter freestyle, finishing second by 0.01 seconds. Still, silver was terrific for the mom who thought she'd retired a few years ago, only to dive back in and become America's first five-time swimming Olympian.

Then Torres was part of the 400 medley relay squad that finished behind Australia. That silver upped her total to three medals here and 12 for her career. In the morning's other final, Oussama Mellouli won Tunisia's first Olympic swimming gold medal, denying Aussie Grant Hackett's bid for a third consecutive title in the 1,500-meter freestyle.

With 32 medals still to be decided Sunday, the United States is atop the medals table with 57. China was second with 49 and first in gold with 27; the U.S. team has 17, nearly half by Phelps.

Men's basketball

An emotional Yao Ming scored 25 points to lead China past Dirk Nowitzki and Germany 59-55 to reach the brink of the medal round -- but you would've thought they'd clinched a medal by the way they celebrated afterward.

"We fought hard to the end," said Yi Jianlian of the New Jersey Nets, who added nine points and 11 rebounds. "Now we need to keep pushing ahead."

Manu Ginobili scored 32 and Luis Scola added 20, leading reigning Olympic champion Argentina past winless Iran 97-82, and Andrew Bogut had 22 and eight rebounds to help Australia past European champion Russia 95-80.

Mindaugas Lukauskis scored 20 points to keep Lithuania undefeated with an 86-73 victory against Croatia, and African champion Angola dropped to 0-4 with a 102-61 thrashing by Greece.

Men's volleyball

The U.S. beat China in three sets, but the bigger news was coach Hugh McCutcheon rejoining the team a week after a knife attack that killed his father-in-law and wounded his mother-in-law. The woman, Barbara Bachman, arrived in her home state of Minnesota on Friday for treatment at the Mayo Clinic.

After the final point, Riley Salmon embraced his coach. McCutheon joined in a team high-five on the court.

"I wouldn't have come back if I wasn't ready to come back," McCutcheon said. "It's what I do -- get out on the sidelines and get the boys fired up."

The Americans went 3-0 without their coach, clinching a spot in the quarterfinals before he returned.

Softball

The American juggernaut crushed another opponent, with Jessica Mendoza hitting her third home run in two days and Jennie Finch pitching five shutout innings for a 7-0 victory over Taiwan. They've outscored their foes 36-1, have allowed just four hits in 29 innings, and have now won 19 straight Olympic games.

"USA is too strong to defeat," Taiwan coach Chang Chia-Hsing said.

In other games, Japan beat China 3-0, Australia beat the Netherlands 8-0 and Venezuela, playing in its first Olympics, stunned Canada 2-0.

Baseball

It was another one-run game for the Americans, although this time they wound up on top -- after erasing a four-run deficit.

Brian Barden homered and had a tying double, then Terry Tiffee doubled in the go-ahead run with two outs in the seventh in a 5-4 victory over Canada.

Barden played in place of injured second baseman Jayson Nix a day after Nix fouled a ball off his left eye and needed micro surgery that will keep him out the remainder of the Olympics.

The Netherlands beat China 6-4 and South Korea beat Japan 5-3.

Boxing

Americans Shawn Estrada and Luis Yanez lost, leaving only two U.S. fighters in the tournament.

Yanez tied his match against Mongolia's Serdamba Purevdorj after three rounds, but couldn't pull it out.

Estrada lost to James Degale, the hard-punching Brit known as "Chunky."

Beach volleyball

Two U.S. men's teams remain on course for a showdown in the finals.

Reigning world champions and heavy gold-medal favorites Phil Dalhausser and Todd Rogers of the United States overcame mental mistakes, mis-hits and an 0-6 deficit in the first-to-15 final set to beat a Swiss pair.

Later, Jake Gibb and Sean Rosenthal had a much easier time getting past a Spain team.

Water polo

Do you believe in ... the U.S. men's water polo team?

After raising doubt with a loss to Serbia, they showed strong defense in knocking off world No. 1 Croatia 7-5. The Croats came in having won three games by a total of 15 goals.

"They've got to know now that if they play like that, they can win this thing," U.S. coach Terry Schroeder said.

The Americans must knock off Germany to earn a spot in the quarterfinals.

Weightlifting

American Cheryl Haworth was sixth in the women's super heavyweight division. Jang Mi-ran of South Korea broke three world records on the way to gold and the unofficial title of the world's strongest woman.

"I am a big girl but that's a lot of weight," said Haworth, who won a bronze medal in Sydney 2000.

Women's field hockey

The U.S. women got their first win of the tournament, beating winless New Zealand 4-1. With one game left, the Americans still have a chance of making the semifinal round.

Doping

Fani Halkia, the reigning Olympic champion in the women's 400-meter hurdles, told reporters she was "shocked" to learn she had tested positive for the banned substance methyltrienolone and would be unable to defend her gold medal.

Halkia spoke to Greek journalists early Sunday morning at a central Beijing hotel. She said she was summoned by the head of Greece's Olympic delegation and told of the results of the first sample she gave to World Anti-Doping Agency doctors.

"I am shocked," she said, according to Greek media reports. "I have undergone more testing than anyone else."

Halkia was tested a few days before the Beijing Olympics in Japan, where Greece's track and field team had been training. She said she had volunteered to take part in WADA's pilot program in which athletes submit themselves voluntarily to regular testing.

Halkia, who has moved out of the Olympic Village, said she was sorry she could not take part in the games and that she had expected to make the 400-meter hurdles final.

Preliminaries in that event were scheduled to begin Sunday afternoon.

Halkia said she did not know how the banned substance was found in her sample.

A total of 15 Greek athletes, including Halkia, have tested positive for methyltrienolone. They include 11 weightlifters, swimmer Yannis Drymonakos, 400-meter runner Dimitrios Regas, and sprinter Tassos Gousis, who was sent home a few days before the Olympics. The International Olympic Committee has also barred sprinter Katerina Thanou from the games for her role in a drug-testing scandal at the Athens Games four years ago.

Halkia was a relative unknown before she won the gold medal in the women's 400-meter hurdles at the 2004 Summer Olympics in Athens. Her semifinal time of 52.77 established an Olympic record.
