LONDON — Five things to know about Monday, Day 3 of the London Olympics:

• Franklin, Grevers win backstroke golds for U.S.

• China takes 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.

No problem.

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.

Fifteen-year-old Ruta Meilutyte of Lithuania got the win in the 100 breaststroke, holding off a late charge from world champion Rebecca Soni of the United States.

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.

Tennis

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.”

Basketball

The French women had the most surprising win of the day, edging Australia 74-70 in overtime. Emilie Gomis scored all 22 of her points after halftime.

Belinda Snell connected from just past half court at the end of regulation, giving Australia a chance. But the Aussies had to play the extra session without stars Lauren Jackson and Liz Cambage — both had fouled out.

China, Turkey, Russia and Canada also won on the women’s side.

Boxing

Light heavyweight Damien Hooper rallied from a third-round deficit for a 13-11 victory over Marcus Browne, handing the U.S. team its first loss in London after a 4-0 start.

Hooper and Browne put on perhaps the best three minutes of the day after both fighters cautiously fought the first two rounds. The Australian raised his aggression in the third to overwhelm Browne, a Staten Island, N.Y., product.

Volleyball

The U.S. women’s team beat Brazil in an early rematch of the Beijing Games final.

Destinee Hooker had 23 points and Jordan Larson added 18 for the top-ranked Americans, who won 25-18, 25-17, 22-25, 25-21 to improve to 2-0 in pool play at Earls Court.

Sheilla Castro had 15 points for No. 2 Brazil, which was energized after a third-set victory but lost on Logan Tom’s floater in the fourth set.

The American women have never won an Olympic gold medal in volleyball.

Beach Volleyball

Two-time gold medalists Misty May-Treanor and Kerri Walsh Jennings earned their 16th consecutive Olympic victory, beating the Czech Republic in straight sets.

It was May-Treanor’s 35th birthday when the match started, but because of TV schedules and a long match earlier in the session, it ended shortly after midnight Tuesday.

Jake Gibb and Sean Rosenthal lost to Poland in pool play, the first setback for the American men or women in beach volleyball at the games.

Equestrian

Zara Phillips, Queen Elizabeth II’s granddaughter, raced through the difficult and dangerous cross-country portion of her first Olympic equestrian eventing competition, finishing clean and well under the pace time.

Princes William and Harry watched her from the main equestrian arena, joined by William’s wife, Kate, and Camilla, the wife of Prince Charles. Seated alongside them were Princess Beatrice and Princess Eugenie, the daughters of Prince Andrew.

Water Polo

This was quite the Olympic debut for Maggie Steffens, who scored seven goals to lead the U.S. women’s team to a 14-13 victory over Hungary.

Despite a team full of veterans, it was the 19-year-old Steffens who led the way with sharp shooting from outside for the Americans, who are looking to win their first gold in the event.

Diving

China is dominating the diving boards — again.

Cao Yuan and Zhang Yanquan totaled 486.78 points in the men’s 10-meter synchronized platform, giving the country its second gold medal in the sport at the games.

German Sanchez and Ivan Garcia of Mexico had the highest degree of difficulty in the competition and it paid off with the silver.

Nick McCrory and David Boudia of the U.S. took the bronze with 463.47. The Americans are 2 for 2 after Abby Johnston and Kelci Bryant earned a silver in 3-meter synchro springboard Sunday, ending a 12-year medal drought.

Rowing

Australia was strong in the men’s four at the rowing regatta, setting one of two Olympic-best times on a sunny final day of heat racing.

Britain, which has won this event at the last three games and is also the world champion, won the second heat and United States took the third heat.
