American Will Claye got the silver and then proposed to American sprinter Queen Harrison.

The American runner-up in triple jump celebrated his medal by jumping into the stands at the Olympic stadium, getting down on one knee and proposing to Harrison.

She said yes.

Engagements are all the rage these Olympics.

Only two days earlier, China’s He Zi had the silver medal slipped around her neck when her boyfriend pulled out a ring and asked her to marry him.

Last week, after a rugby match, the girlfriend of Brazilian player Isadora Cerullo went down to the field and asked Cerullo to marry her.

The anti-doping laboratory in Beijing is re-opened for testing after a ban of nearly four months.

The World Anti-Doping Agency says it lifted a suspension and reaccredited the lab to test urine and blood samples.

The suspension meant much testing of Chinese athletes ahead of the Rio de Janeiro Olympics was taken out of China’s hands.

WADA did not specify exactly which working standards the Beijing lab had failed to merit a ban, though said “five remedial steps” were now achieved.

Labs also temporarily suspended year or still closed down include the Rio lab, and others in Russia, Spain, South Africa, Portugal and Kazakhstan.

The United States women’s field hockey team placed fifth at the Olympics, the program’s best finish in 20 years.

The Americans lost their quarterfinal match to Germany on Monday. Their final ranking is based on their second-place finish in pool play.

The Americans also placed fifth at the 1996 Games in Atlanta. Their only better finish was third at the 1984 Games. This year’s squad set program records for most wins in pool play with four, and most goals in an Olympic match, with six against Japan.

The Americans defeated No. 2 Argentina and No. 3 Australia in their first two matches, then knocked off Japan and India to take the lead in Pool B. The United States led its final pool match against Britain heading into the fourth period before losing 2-1.

Britain could claim three more gold medals and five more total after its riders all advanced through preliminary rounds during the morning track cycling session at the Rio Games.

Becky James and Katy Marchant swept through the women’s sprint quarterfinals, and Jason Kenny and Callum Skinner are alive in the keirin. Laura Trott leads the multidiscipline omnium.

Track cycling concludes with the finals in all three events Tuesday night.

IOC president Thomas Bach took in the session with UCI president Brian Cookson, the head of cycling’s world governing body. Bach also turned out to watch the end of the Olympic road race.

Floyd Mayweather Jr. is still the biggest star at the Olympic boxing tournament.

The U.S. bronze medalist at the 1996 Atlanta Games was back to watch another day of fights. He smiled when he was shown and introduced on the big screen to a roaring ovation. Dozens of fans hurried his way for pictures. He never took the earbuds attached to his mobile phone out of his ears when he posed for a few fans.

They were quickly shooed away and blocked off by members of Mayweather’s friends known as TMT: The Money Team.

Mayweather invited Popo Freitas, a former Brazilian boxing world champion, down to his seat for a quick chat.

He seemed to enjoy the fights from the front row of the bleacher seats. There are no ringside seats at the venue.

The 39-year-old Mayweather retired last year after a 49-0 career. The International Boxing Association (AIBA) changed its rules this year to allow professionals to fight at the Olympics, but Mayweather had no interest.

Mayweather has dropped in once or twice since he arrived for the Rio Games.

Netherlands has finished off a sweep of the Olympic open water swimming races with a thrilling victory in the men’s 10-kilometer race.

Ferry Weertman captured the gold medal at Copacabana after Greece’s Spiros Gianniotis crossed under the finish line first but reached up after the Dutchman to touch the timing pad.

That gave the victory to Weertman in a time of 1 hour, 52 minute, 59.8 seconds, one day after Sharon van Rouwendaal took the women’s race for the Netherlands.

Gianniotis missed a chance to give Greece its first swimming gold since the inaugural Olympics in 1896.

The bronze went to France’s Marc-Antoine Olivier, who out-touched China’s Lijun Zu. American Jordan Wilimovsky was fifth.

Australia’s Jarrod Poort broke away from the pack early in the race, building a lead of more than a minute at the midway point. He couldn’t hold on, getting passed on the last of four laps and finishing 20th.

The morning after the stunning win of Thiago Braz da Silva in the men’s pole vault, home favorite Fabiana Murer failed to qualify for the women’s final.

With three fouls on her opening of 4.55 meters, Murer ended up with no measure. Her personal best is 4.87, and the height in sunny, windless conditions should not have posed too many problems.

MEDAL ALERT: Ferry Weertman has given the Netherlands a sweep of the Olympic open water swimming events, winning the men’s 10-kilometer race at the Rio Olympics. Spiros Gianniotis of Greece takes the silver and France’s Marc-Antoine Olivier claims the bronze.

Taoufik Makhloufi had little time to enjoy his 800 meter silver medal at the Olympics. Tuesday morning, barely 12 hours later, it was back to work, qualifying for the 1,500 semifinals. The Algerian made sure he won his heat in 3 minutes 46.82 seconds, almost 20 seconds slower than his personal best. And almost 8 seconds behind the qualifying time of Kenyan favorite Asbel Kiprop.

Still, silver around his neck boosted his confidence for a second medal. “This gives me great hope for the 1,500. It’s like a bonus,” he said. “It is the first time to do 800 and 1500 in a big championship.”

Christian Taylor and Will Claye have done it again, sweeping gold and silver in the triple jump for the United States at back-to-back Olympics.

Taylor successfully defended the Olympic title he won in London in 2012, setting down the benchmark on Tuesday with a season-leading mark of 17.86 on his first attempt. He posted the three best jumps of the competition.

Claye finished with silver again with a personal record of 17.76. He also won a bronze in the long jump at London, when he was the first man since 1936 to win medals in both the horizontal jumps.

World indoor champion Dong Bin of China won bronze in a personal record 17.58.

MEDAL ALERT: Christian Taylor has successfully defended his Olympic triple jump title, leading Will Claye in a repeat U.S. sweep of gold and silver medals.

Taylor, who won gold in London in 2012 at 17.81, set the benchmark on Tuesday with a season-leading mark of 17.86 on his first attempt.

Claye was second again and Dong Bin of China won bronze.

10:55 a.m.

Interim President Michel Temer, who was loudly booed by Brazilians at the Olympics’ opening ceremony, won’t have to face the same jeering crowds when the games come to an end.

His press office said Tuesday that he won’t attend the closing ceremony, ending days of speculation after he told journalists last week that he should go. A presidential spokesperson told The Associated Press that it’s not protocol for a head of state to attend the games’ farewell.

Some Brazilian media are taking Temer’s absence as a diplomatic snub after Japanese Prime Minister Shinzo Abe said he would attend the closing ceremony to represent Tokyo, which is hosting the 2020 Summer Games.

Temer has kept a low profile since taking over from the suspended President Dilma Rousseff in May. The closing ceremony Aug. 21 comes just a few days before the Brazilian senate is schedule to vote whether to impeach Rousseff.

While Brazilians blame Rousseff for widespread corruption in her Workers’ Party and for steering the economy into its deepest recession in decades, they haven’t warmed to her replacement. From day one, the games have been marked by Brazilians bringing signs to venues reading “Fora Temer,” a call for the removal of the politician who many accuse of trying to gain power he could never have obtained at the ballot box.

The last canoe medals handed out Tuesday had a royal gloss.

Crown Prince Frederik of Denmark placed the gold, silver and bronze medals around the necks of the winners in the men’s 1,000-meter kayaking singles event.

Frederik is a member of the international Olympic Committee. He’s an avid sportsman who practices sailing, tennis, running, golf, triathlon and skiing.

Perhaps the crown prince was expecting to hand out a medal to a compatriot. But Rene Holten, the Danish world champion in the event, didn’t have a good race, and finished sixth in the final.

Fresh from her world-record setting victory in the 10,000-meters, Almaz Ayana embarked on the second step for a distance double at the Rio Olympics with a comfortable win in her heat of the 5,000.

The 24-year-old Ethiopian, the world champion in the 5,000, surged away from the pack with seven laps to go in heat 2 and led all qualifiers in 15 minutes, 4.35 seconds on Tuesday — 13 seconds clear of countrywoman Senbere Tefere, the world championship silver medalist.

Vivian Cheruiyot of Kenya, the Olympic silver medalist in the 5,000 and two-time world champion, was next in 15:17.74.

With the first five in each heat and the next five fastest advancing to Friday’s final, there was plenty of jostling for positions.

Two of the casualties were American Abbey D’Agnostino and Nikki Hamblin of New Zealand, who tangled and both ended up on the track in the second heat. D’Agnostino got up to help Hamblin, who was sprawling on the ground. Then as D’Agnostino hobbled on what appeared to be a right ankle injury, Hamblin tried to help her continue.

In the end, Hamblin finished in 29th place, one ahead of D’Agostino. The pair embraced at the finish, before D’Agostino was taken from the track in a wheelchair.

10:35 a.m.

Marcus Walz of Spain has won a surprise gold medal in the men’s 1,000-meter kayaking singles.

The 21-year-old Spaniard saved his best for last after placing third in both of his qualifying heats in the event.

In the final Tuesday he surged from the back of the field to win in 3 minutes, 31.447 seconds.

Josef Dostal of Czech Republic was second and Roman Anoshkin of Russia took the bronze.

The Oxford, England-born Walz had never won a major title in the event and was going up against a field of Olympic, world and European medalists.

10 a.m.

Lisa Carrington has proved once again she’s the world’s fastest kayaker.

The New Zealander won her second straight gold in the women’s 200-meter flatwater race, a furious sprint where paddlers go full throttle for about 40 seconds.

Carrington is also a four-time world champion in the event.

She won the race in 39.864 seconds, ahead of silver medalist Marta Walczykiewicz of Poland and Inna Osipenko-Rodomska of Azerbaijan, who got bronze.

Earlier, Hungarian kayakers Gabriella Szabo and Danuta Kozak won the gold medal in the women’s 500-meter double, edging Germany’s Franziska Weber and Tina Dietze by just 5 hundredths of a second. Poland took third place.

9:25 a.m.

Sebastian Brendel of Germany beat Brazil’s Isaquias Queiroz to win his second consecutive gold medal in the men’s 1,000-meters canoe sprint.

Brendel and Queiroz were neck-and-neck Tuesday for most of the race but the German pulled ahead in the final 250 meters. Serghei Tarnovschi of Moldova got the bronze.

The crowd at Lagoa stadium roared for Queiroz, who was chasing Brazil’s first gold in flatwater canoeing. The Brazilian’s nickname is “Sem Rim,” or missing kidney, because he lost one kidney after falling from a tree at age 10.

Queiroz will also race in the men’s 200-meter sprint and the 1,000-meter doubles.

On Day 11 of the Rio Olympics, Simone Biles is seeking a fourth Olympic gold, one of 28 to be handed out.

Her challenge Tuesday comes in the floor exercise, where the American gymnast will try to fend off teammate Aly Raisma. Biles has already earned three golds — and a bronze Monday night when she wobbled during the balance beam final.

On the men’s side, Oleg Verniaiev leads on parallel bars while Epke Zonderland of the Netherlands will try to defend his Olympic high bar title.

Five gold medals are up for grabs in track events, including women’s 1500 meters and discus, and men’s high jump, triple jump and 100-meter hurdles.

At the Rio velodrome, the British team is hoping for big things. Jason Kenny is going for his third gold in Rio, this time in the keirin; Katy Marchant and Becky James are in the individual sprint and Laura Trott is favored to defend her title in the women’s multi-event omnium.

Semifinals are taking place in women’s soccer and in men’s and women’s beach volleyball; knockout play begins in women’s basketball, with the U.S. facing Japan; and the men are swimming in the open ocean off Copacabana beach.

7:30 a.m.

Brazilians love the beach — and they are really loving the beach volleyball competition at the Rio Olympics.

That’s because Brazil has three entries in Tuesday’s men’s and women’s semifinals, including Alison Cerutti and Bruno Oscar Schmidt, who eliminated Americans Phil Dalhausser and Nick Lucena on Monday night. The Brazilians will face the Dutch team of Alexander Brouwer and Robert Meeuwsen.

On the women’s side, Kerri Walsh Jennings and April Ross of the United States play Tuesday for a spot in the gold-medal game when they meet Brazilian world champions Agatha and Barbara at the stroke of midnight on the beach.

Larissa Franca Maestrini and Talita Rocha of Brazil take on Germans Laura Ludwig and Kira Walkenhorst in the other women’s semifinal.

Walsh Jennings is going for her fourth gold, and Ross is looking to improve on the silver she earned at the 2012 London Olympics.

6:50 a.m.

It’s the men’s turn to take to the sewage-filled waters off Copacabana beach for their 10-kilometer (6.2-mile) open water race.

Rio de Janeiro is only the second Olympics holding the competition in open ocean waters. At the first Summer Games in 1896, before custom-built pools were the norm, swimming was held in Greece’s Bay of Zea.

The inaugural open water event in 2008 was staged at Beijing’s rowing and canoeing canal and the open water swim in 2012 took place in Serpentine lake at London’s Hyde Park.

On Monday, Brazil’s Poliana Okimoto won bronze in the open water swim when France’s Aurelie Muller was disqualified for colliding with another swimmer. It was the first Olympic swimming medal ever won by a Brazilian woman.

Sharon van Rouwendaal claimed gold for the Netherlands.

6:20 a.m.

Knockout play at the Olympics is often nerve-wracking — but not so far for the U.S. women’s basketball team in Rio.

The U.S. women begin their knockout stage Tuesday, facing Japan in a quarterfinal after cruising through the pool play in Rio, winning five games by an average of 40.8 points.

The American women have won 46 consecutive games in the Olympics and are three victories away from a sixth consecutive gold medal.

The Japanese women did beat the U.S. team once — but that took place back in 1976.

In other women’s Olympic basketball quarterfinals, Australia plays Serbia, Spain plays Turkey and France faces Canada.

Not too many athletes can be slammed into the hard track of the Olympic velodrome at a high speed, bike and body sprawling in all directions, and get up and finish a 160-lap course to win gold.

But Elia Viviani of Italy is not just any athlete.

After the crash Monday night, Viviani realized he wasn’t hurt and he was still leading the final race in the omnium — the six-event, two day men’s competition.

So Viviani hauled himself back onto his bike and held off stiff challenges from British cycling star Mark Cavendish and reigning gold medalist Lasse Norman Hansen of Denmark.

“It’s a bike race,” Viviani said of the crash, caused when Cavendish collided with Korean rider Park Sang-hoon. “We’re on a track, no brakes. When one guy changes directions in front of you and someone else is not ready to change directions, you crash.”

For decades, coaches have told sprinters to ‘lean in’ at the finish line.

Shaunae Miller of the Bahamas went one step further at the 400 meters in Rio: she dived head-first. The surprising move earned the 22-year-old Miller a gold medal and stunned American Allyson Felix, denying Felix a fifth career gold medal.

Miller had taken an early lead, then held off Felix’s charge along the straightaway. Neck-and-neck with two steps to go, Miller tumbled across the line to win by .07 seconds.

Miller says didn’t plan one of the most dramatic images seen at the Rio Olympics.

“I don’t know what happened. My mind just went blank,” Miller said. “The only thing I was thinking (about) was the gold medal, and the next thing I know, I was on the ground.”

He’s feeling good. And that’s never good for his competition.

The heats for Usain Bolt’s favorite race — the 200 meters — are beginning Tuesday at the Rio Olympics and the Jamaican sprinter is remarkably relaxed.

“I’m always confident going into the 200 meters,” said Bolt, who surged past Justin Gatlin to win the 100 meters on Sunday, his seventh Olympic gold.

Also Tuesday, American Christian Taylor will try to defend his triple jump title, while Jamaica’s Omar McLeod and American Devon Allen, the University of Oregon football/track standout, are among those seeking gold in the men’s 110-meter hurdles.

Medals also will be awarded in the women’s discus, the women’s 1500 meters and the men’s high jump.

On most days at the Summer Olympics, the talk focuses on times and medals and world records.

On Monday in Rio de Janeiro, it was all about the weather.

High winds and driving rain flipped sailboats over like tub toys, caused throwers to foul or release their discus early, threw pole vaulters off their stride and made running on parts of the Olympic track like splashing through puddles.

The 110-meter hurdles heats were hard hit, prompting organizers to run a special race later in the night for those who did not quality when the weather was the worst.

“It’s atrocious. It’s hard to compete in weather like this,” said Jamaican hurdler Omar McLeod, who won the first heat amid heavy rain. “The water is beaming down in your face and your eyes and it’s real hard.”

Some sailing races were canceled and the boats raced to get back to shore safely.

At the Olympic Stadium, someone had some fun: “Singin’ in the rain” was blaring on loudspeakers.

The Russian runner who blew the whistle on Russia’s doping scandal fears for her safety and has switched residences after hackers breached a database that records her whereabouts.

Yulia Stepanova and her husband, Vitaly, spoke up about a state-run doping system in Russia that led to the ouster of the country’s athletes from the Rio Olympic track meet.

Recently, their email was hacked and the password stolen for Stepanova’s account on a database controlled by the World Anti-Doping Agency. Like hundreds of athletes, Stepanova accesses the WADA system to enter her whereabouts, so doping-control officers can find her if she’s selected for out-of-competition testing. The database also contains personal contact information, such as phone numbers and addresses.

Stepanova told reporters Monday “if something happens to us, you should know it’s not an accident … we are trying to take every measure possible to keep ourselves safe.”

Brazilian female athletes are shining at the Rio Olympics — and people here are paying attention, some for the first time.

In a country where men’s soccer is king, Brazilian women have found it difficult to find their place in sports because of the lack of athletic programs, funding and what they call unfair marketing decisions that promote men.

But now each victory of Brazil women’s soccer team is being savored. And when Rafaela Silva won gold in women’s judo — Brazil’s first gold medal of this Olympics — major newspapers splashed her photo on their front pages.

The country’s most famous female soccer player, Marta, told reporters “all the love we are getting during the Olympics, we hope that it doesn’t go away … with that much-needed support, women’s soccer can grow.”

Her team faces Sweden in Tuesday’s semifinal.
