LONDON (AP) — Five things to know about Monday, Day 3 of the London Olympics:
—Franklin, Grevers win backstroke golds for U.S.
—China wins 2nd straight Olympic gold in gymnastics.
—Williams sisters, Federer, Roddick advance at Wimbledon.
—Swiss Olympic team boots soccer player for racist tweet.
—Colombia player suspended for Wambach punch
There was backstroke dominance for the United States and another impressive French performance during another wild night at the Olympic pool.
American teenager Missy Franklin won the women's 100-meter backstroke before Matt Grevers led a 1-2 finish for the U.S. in the same men's race.
Franklin, a 17-year-old from Colorado and best hope for the U.S. program in the post-Michael Phelps era, had a brief 13-minute break after taking the final qualifying spot in the 200 freestyle semifinals before she had to get back into the water for the backstroke final.
Australia's Emily Seebohm, the top qualifier, led at the turn and was under world-record pace, but Franklin showed a remarkable finishing kick. With her arms twirling, the 6-foot-1 swimmer passed the Aussie in the final 25 meters and lunged toward the wall for a winning time of 58.33 seconds.
Grevers then produced another rally in the men's 100 backstroke and Nick Thomas made it a 1-2 finish for the Americans, touching for silver in 52.92.
The twin backstroke victories made up for a disappointing performance by U.S. star Ryan Lochte, who faded to fourth in the loaded 200 freestyle — won by France's Yannick Agnel.
The towering Agnel was in front throughout in perhaps the most star-studded race of these games — even without Michael Phelps, who passed up a chance to defend his Olympic title.
The Chinese won their second straight Olympic title in gymnastics and third in four games after a dismal performance in qualifying.
China's score of 275.997 points was more than four points better than Japan, which needed help from a replay to finish second.
Britain initially was announced as the silver medalist, setting off raucous celebrations at the O2 Arena, Princes William and Harry included. The British don't have a proud history in gymnastics, and this was their first men's team medal in a century.
But Japan questioned the score of three-time world champion Kohei Uchimura on pommel horse, the very last routine. While judges huddled around a video screen, the British partied and Uchimura and his teammates sat stone-faced against a wall.
About five minutes later, Uchimura's score was revised, with judges giving him seven-tenths more credit for his dismount. Instead of 13.466, he scored 14.166 — enough to move Japan from fourth to second with a total of 271.952. Britain was bumped down to bronze.
There was a familiar sister act at Wimbledon on Monday, with Serena and Venus Williams each advancing in the singles tournament, then combining for a doubles win.
Other major champions to advance in singles included Roger Federer, Lleyton Hewitt, top-seeded Victoria Azarenka, Kim Clijsters, Petra Kvitova, Ana Ivanovic and three-time Wimbledon runner-up Andy Roddick.
Venus Williams waited an extra day because of rain to begin her bid for a record fourth gold medal in Olympic tennis, then defeated recent French Open runner-up Sara Errani of Italy 6-3, 6-1. Serena completed a July sweep of Poland's Radwanska sisters by beating Urszula in the second round, 6-2, 6-3. She defeated Radwanska's sister, Agnieszka, in the Wimbledon final this month. Federer also reached the third round, beating Julien Benneteau of France 6-2, 6-2.
"What a good day for fans between me, Venus, Roger and all the other players," Serena Williams said. "It's really such a great experience."
Also Monday, Switzerland stripped a soccer player of his Olympic accreditation after he sent a threatening and racist message on Twitter about South Koreans. The comments by Michel Morganella came hours after the Swiss lost to South Korea, 2-1, on Sunday.
The 23-year-old player said in the tweet that South Koreans "can go burn" and referred to them as a "bunch of mongoloids."
Swiss Olympic team chief Gian Gilli said via a translator at a news conference that Morganella "discriminated against, insulted and violated the dignity of the South Korea football team as well as the South Korean people.
Morganella later released a contrite statement through the Swiss Olympic team: "I am sincerely sorry for the people of South Korea, for the players, but equally for the Swiss delegation and Swiss football in general. It's clear that I'm accepting the consequences."
Morganella is the second athlete kicked off an Olympic team in London for offensive Twitter comments. Last week, triple jumper Voula Papachristou was kicked off Greece's Olympic team for her comments on Twitter mocking African immigrants and expressing support for a far-right political party.
A group of Olympians turned to Twitter to protest a rule that limits their ability to market themselves during the games.
American sprinter Sanya Richards-Ross is among the competitors taking part in the campaign, using the hashtags "WeDemandChange2012" and "Rule40."
Rule 40 is the IOC policy barring Olympic athletes from using their names or likenesses for advertising during the games. The rule is in effect from July 18-Aug. 15, three days after the closing ceremony.
"I've been very fortunate to do very well around the Olympics, but so many of my peers struggle in this sport," Richards-Ross said Monday. "And I just think it's unjust."
The IOC says it pours 94 percent of its commercial revenue back into sports, and is only trying to protect the money that comes into the Olympic movement.
"A huge number of 10,500 athletes who are here would understand why we are doing this," spokesman Mark Jones said. "For one month, we ask them not to endorse products not related to the Olympics that don't actually give money back to the movement."
A Colombian soccer player was suspended for two games after U.S. forward Abby Wambach said she was "sucker-punched" in the right eye by Lady Andrade during the 3-0 win by the U.S. on Saturday. Wambach called for FIFA to take action, while Andrade called it "an accident."
FIFA says its disciplinary committee suspended Andrade for a group match Tuesday against France and for the quarterfinals if Colombia advances.
