Carol Huynh of Canada is carried off by unidentified members of the Canadian delegation after defeating Japan's Chiharu Ichu in the final of 48kg women's freestyle wrestling competition at the Beijing 2008 Olympics in Beijing, Saturday. Huynh won the gold.

BEIJING — Canada's Carol Huynh, a frequent world placewinner but never a champion, has upset 2004 silver medalist Chiharu Icho of Japan to win the Olympic women's wrestling 48-kilogram gold medal.

Huynh is Canada's first gold-medalist in the Beijing Olympics.

Icho, second for a second successive Olympics, is the sister of Athens 63-kilogram gold medalist Kaori Icho, who wrestles Sunday.

The bronze medalists were Mariya Stadnik of Azerbaijan and 2004 gold medalist Irini Merlini of Ukraine.

Merlini pinned Clarissa Chun, the Hawaiian who lost a three-period decision to Icho in the semifinals. Merlini lost in the quarterfinals to Icho, a reversal of Merlini's 2004 gold-medal win.

Elsewhere at the Olympics on Saturday morning:

• The U.S. men's volleyball team 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.

"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."

• At the Bird's Nest, Russia's Valeriy Borchin won the 20-kilometer walk, upstaging the defending champion; and U.S. sprinters Lauryn Williams, Torri Edwards and Muna Lee advanced to the quarterfinals of the women's 100-meter dash.

• American Keith Sanderson was in first place after qualifying in the men's 25-meter rapid-fire pistol, but he wound up fifth. Ukraine's Oleksandr Petriv won it.

• Americans Phil Dalhausser and Todd Rogers advanced to the quarterfinals in beach volleyball with a tight three-set win over a Swiss pair. Heavy favorites to win the gold medal in their Olympic debuts, Dalhausser and Rogers have won three straight since getting upset by 23rd-seeded Latvia in their opener.

•n China's gold count is about to go up with two women competing in the badminton finals.

From Friday's action in Beijing:

Nastia Liukin and Shawn Johnson finished 1-2 in the all-around — a reverse of their usual order of finish in this event.Johnson was tops at the world championship, the national championships and at the Olympic trials only a few weeks ago. But not when it counted most."There is nothing bigger or greater than this," Liukin said.

Tyson Gay coasted through two 100 meter preliminary heats, showing his left hamstring is just fine six weeks after hurting it at the U.S. Olympic trials.World record-holder Usain Bolt and the guy he took it from, fellow Jamaican Asafa Powell, also advanced easily to the final 16. All three are expected to make Saturday's final — perhaps the most highly anticipated event of the 10-day track and field meet at the Bird's Nest.In the semis, Powell and Gay will run the same heat, while Bolt's biggest challenge in the other semi figures to be from America's Walter Dix and Derrick Atkins of the Bahamas."I feel pretty good. It felt pretty relaxed," Gay said after his second race. "I just wanted to make it through."Tirunesh Dibaba of Ethiopia won the 10,000 meters in an Olympic record 29 minutes, 54.66 seconds. Turkey's Elvan Abeylegesse took silver, while Shalane Flanagan set an American record at 30:22.22 to win bronze. It was the first U.S. medal in the 10K since 1992.In the men's 1,500, Bernard Lagat, Leo Manzano and U.S. team flagbearer Lopez Lomong all made it out of their first races.The men's shot put was a big disappointment for the Americans. Instead of sweeping, they got only a silver from Christian Cantwell. Poland's Tomasz Majewski won gold.Reese Hoffa, the reigning world champion, was seventh and his U.S. teammate Adam Nelson, the two-time Olympic silver medalist, threw with hurt ribs and didn't make it into the final eight.

Turns out, the U.S. women are as dominant as ever.First they set an Olympic record with four homers in a 7-0 victory over Japan. Then they resumed a rain-stopped game against Canada, trailing 1-0. After being five outs from losing, they wound up winning by the lopsided score of 8-1.The Americans broke the game open with four runs in the sixth, helped by two errors by Canadian shortstop Jennifer Salling, and a wild pitch and hit batter by Dione Meier of Canada, which beat China 1-0 earlier in the day.

The U.S. women started slowly, then got clicking, pounding Spain 93-55. Tina Thompson scored nine of her 17 points during a game-breaking 20-5 run in the third quarter.
