RIO DE JANEIRO » The Latest on the 2016 Summer Olympics in Rio de Janeiro (all times local):

6:55 p.m.

No more throwing volleyballs into the stands at the Copacabana venue.

After a collision going for one of the signed souvenirs earlier today, organizers are now pulling a child out of the stands and having a member of the winning team hand them the ball.

The new system makes for feel-good video and eliminates the chaos of fans fighting for the ball.

For the first few days, the winning team would be given a ball to sign and kick, throw or hit into the stands. A nasty collision later, the process was changed.

6:55 p.m.

The International Olympic Committee has stripped a Ukrainian javelin thrower of his silver medal from the 2012 London Olympics after he tested positive in a new analysis of his doping samples.

The committee says Oleksandr Pyatnytsya tested positive for the steroid turinabol and was retroactively disqualified from the games and ordered to return his medal.

He was one of four more athletes sanctioned by the IOC today after the retesting of stored samples from London and the 2008 Beijing Games. A total of 98 athletes were caught in those retests.

Also disqualified today were Turkish weightlifter Nurcan Taylan, Armenian weightlifter Hripsime Khurshudyan, and Belarusian hammer thrower Pavel Kryvitski. None of those were medalists.

6:35 p.m.

SPOILER ALERT: The U.S. women’s gymnastics team has won gold for a second consecutive Olympics.

The U.S. women’s gymnastics team gave retiring national team coordinator Martha Karolyi a fitting send-off in the Olympic finals, putting on a two-hour display of precision and class. Their score of 184.897 was more than eight points clear of silver medalist Russia, a blowout that Michael Jordan’s “Dream Team” should envy.

6:35 p.m.

For American archer Brady Ellison, there’s no better feeling than moving on — and no worse feeling that it was at the expense of his best friend.

Ellison made it through the second round of the men’s archery tournament today at the Rio de Janeiro Olympics by knocking off teammate/hunting buddy Jake Kaminski. At one point in the match, the second-seeded Ellison put six straight arrows in the top scoring ring in a 6-2 win.

“I look at it two ways: It sucks because you train for years and have an American bracket, just like an American tournament,” said Ellison, who’s been drawing comparisons to actor Leonardo DiCaprio on social media. “On the other side, we advanced someone. For Team USA, it’s good. For the individuals, it sucks.”

6:35 p.m.

American beach volleyball team Brooke Sweat and Lauren Fendrick lost to the defending world champions today and fell to 0-2 at the Olympics.

Larissa and Talita won 21-16, 21-13. The Americans now need to win their final match, against Russia on Thursday, to guarantee themselves of at least one more day on the sand in at the Copacabana venue.

“There’s moments of greatness there,” Fendrick said. “We’ve got to capture that and have that connection more often.”

The United States and Russia are tied with two losses and no victories at the bottom of their pool. The loser of their match is eliminated, and the winner will either advance to the quarterfinals or a play-in game in the “lucky loser” round..

During a referee challenge, the scoreboard put up the wrong names in place of Fendrick and Sweat. It listed them as Kerri Walsh Jennings and partner April Ross.

6:35 p.m.

MEDAL ALERT: South Korean Sangyoung Park stormed back to score the final five points and take gold in men’s epee today in a matchup of the youngest and oldest fencers in the field.

Park, just 20, beat 41-year-old Geza Imre of Hungary Imre 15-14.

Despite the loss, Imre is fencing’s oldest Olympic individual medalist since 1952 when another Hungarian, Aladar Gurevich won the silver in men’s sabre at 42.

Top-ranked Gauthier Grumier won the bronze.

6:25 p.m.

MEDAL ALERT: The U.S. women’s gymnastics team has won gold for a second consecutive Olympics.

6:25 p.m.

Lauren Fendrick and Brooke Sweat already have a lot to live up to as the No. 2 women’s beach volleyball team in the United States. Kerri Walsh Jennings is a three-time gold medalist, and her partner April Ross won the silver medal in London.

So it probably didn’t help when the scoreboard misidentified them as Walsh Jennings and Ross during their match against Brazil today.

During a referee challenge, the scoreboard put up the wrong names. Fendrick seemed to notice, but had bigger concerns. The Americans lost the first set 21-16.

6:25 p.m.

Belarus got into the win column in women’s basketball on Tatyana Troina’s 3-pointer with 52.6 seconds left in a 65-63 victory against Brazil today.

Brazil (0-3) forced a turnover with 14 seconds left, but captain Iziane Castro’s off-balance shot at the buzzer bounced harmlessly off the rim. Still, the loudest and biggest crowd yet at the Youth Arena gave the Brazilians a standing ovation for their effort.

The Brazilians were up 18 points in the second quarter, but Belarus (1-2) fought its way back and turned the final two quarters into a thrilling battle with fans clapping, whistling and yelling at every opportunity.

But Belarus, which lost its first two games by a combined five points, had Troina. She finished with 18 points, hitting 5-of-7 from 3-point range, and scored six of the final eight points for Belarus.

Damiris Dantas led Brazil with 23 points.

6:05 p.m.

Green, not gold, was the color of the day at the Olympic diving venue.

Sure, China won its third consecutive gold medal today, but the buzz was about the color of the water in the diving pool.

It was a murky green, in stark contrast to the pool’s previous day’s color and also that of the clear blue water in the second pool at the venue.

British diver Tom Daley tweeted a photo of the two pools next to each other and captioned it, “Ermmm…what happened?!”

Water quality has been a major issue surrounding the Rio Olympics, but in the ocean and lagoons, not the venue pools.

A statement from Rio 2016 organizers says water tests were conducted and there is no risk to athletes. Organizers say they’re investigating what caused the color change.

6:05 p.m.

MEDAL ALERT: American Travis Stevens has won a silver medal in the men’s 81-kilogram division in judo, losing to Russia’s Khasan Khalmurzaev in the final.

Stevens was in top form today, winning most of his fights by the maximum score in judo, including a hard-fought semifinal where he caught his opponent in a stranglehold, forcing him to tap out in submission. Stevens finished fifth at the London Games and was determined not to leave Rio empty-handed.

Khalmurzaev had not been beaten all year.

The men’s bronze medals were won by Sergiu Toma of the United Arab Emirates and Takanori Nagase of Japan.

5:45 p.m.

MEDAL ALERT: It’s another Olympic diving gold for the Chinese.

Chen Ruolin and Liu Huixia won the women’s 10-meter synchronized platform title today, making China 3-for-3 in the competition so far.

Chen and Liu led all five rounds and totaled 354.80 points, winning by just over 10 points in the closest diving contest yet in Rio.

The Chinese have never lost the event at the Olympics. Chen earned her third consecutive gold medal in 10-meter synchro, having won in 2008 and 2012 with different partners.

Malaysia earned silver with 344.34 points. Canada took bronze with 336.18.

The United States finished seventh among eight teams.

5:45 p.m.

Top seed Slovenian Tina Trstenjak has won the women’s judo gold in the 63-kilogram division, following in the footsteps of fellow Slovenian and London Games champion Urska Zolnir, who is now on her coaching team.

After pinning second-seeded Clarisse Agbegnenou of France to the mat for 20 seconds — just two minutes into the fight — Trstenjak scored an automatic ippon victory today. Trstenjak is a former world judo champion and also holds a European title.

The women’s bronze medals were won by Yarden Gerbi of Israel and Anicka Van Emden of the Netherlands.

5:30 p.m.

The Italian women’s beach volleyball team of Laura Giombini and Marta Menegatti had its first win.

Not just at the Olympics.

In any event since they last played as juniors.

In a sport where teams stay together years so they can learn and anticipate each other’s every move, the Italians were thrown together last week with Menegatti’s regular partner failed a drug test.

Menegatti then had to find an Italian partner who had played in enough qualifying events or risk staying home herself. Today, the pair beat Egypt in straight sets.

In all, they trained together three times before stepping on the sands at the Copacabana venue for their first match on Sunday, a loss to Canada. They are now 1-1 with one match left in pool play.

Giombini says she hadn’t earned her spot in the Olympics, but she still hopes to play well and enjoy it.

5:10 p.m.

WORLD RECORD: China’s Deng Wei broke the world record as she won Olympic weightlifting gold in the women’s 63-kilogram category today.

Deng lifted 147 kilograms in the clean and jerk and 115 in the snatch for a world-record total of 262 across the two lifts.

Silver went to North Korea’s Choe Hyo Sim, who briefly broke the Olympic clean and jerk record at 143, but had finished too far behind Deng in the snatch to challenge for gold. Kazakhstan’s Karina Goricheva took bronze.

Weightlifting has been ravaged by doping in recent years, with the women’s 63kg class particularly badly hit.

Kazakhstan’s 2012 gold medalist Maiya Maneza missed the Olympics after failing a drug test, while two of the top four from last year’s world championships were also out for doping-related reasons.

5 p.m.

There was a Brazilian celebration in men’s basketball after Marcus Marquinhos’ offensive rebound tip-in with 5.5 seconds left in the game gave the host team a 66-65 win over Spain. The boisterous crowd erupted with a deafening, flag-waving celebration.

The Spanish team — silver medalists in 2008 and 2012 — fell to a disappointing 0-2 start to the Rio Games.

Brazil (1-1) led most of the game, but Spain rallied in the fourth quarter and used a 6-0 run late to take its first lead since the second quarter. But Pau Gasol missed two free throws with 23 seconds remaining that left the door open for Brazil.

Marcelinho Huertas led Brazil with 11 points and seven assists while Marquinhos added 10 and the biggest bucket of the night.

Gasol scored a game-high 13 and grabbed 10 rebounds, but was just 5 for 12 from the free-throw line.

5 p.m.

The first day of competition in the Finn class at the Olympic sailing regatta has ended with a jumbled leaderboard thanks to wildly shifting wind coming off Sugarloaf Mountain in the opening race.

Britain’s Giles Scott, the overwhelming favorite, had finishes of 17th and third and is in 10th place overall. Jonas Hogh-Christensen of Denmark, the 2012 silver medalist, went 13-2 and is sixth. American Caleb Paine of San Diego sits eighth after going 7-10.

Scott has been practically perfect the last four years.

Hogh-Christensen said the first race was “a mockery of sport” and should have been abandoned because of the wind, which shifted 40 to 50 degrees.

Slovenia’s Vasilij Zbogar is in the lead after finishes of third and first.

4:40 p.m.

Rafael Nadal’s first tennis tournament in 2½ months is going exactly to plan.

The 14-time Grand Slam champion and 2008 Olympic gold medalist is into the third round at the Rio Games after beating Italy’s Andreas Seppi 6-3, 6-3 today.

Spain’s Nadal had been sidelined since May, when he withdrew from the French Open because of an injured tendon sheath in his left wrist.

He has lost nine games through two matches in singles in Brazil, and is scheduled to play in the third round of men’s doubles later today.

Nadal also is entered in mixed doubles with Garbine Muguruza, the French Open champion who lost in singles today to Puerto Rico’s Monica Puig 6-1, 6-1.

4:25 p.m.

The Brazilian crowd has taken a liking to the Egyptian women’s beach volleyball team.

Overmatched on the sand, the partnership of Doaa Elghobashy and Nada Meawad lost their second match in as many tries today.

But they stood out in their full-length uniforms ?— Elghobashy also wears a hijab —? amid all the bikinis and board shorts.

The crowd serenaded the players with “E-Gi-To!” during their points.

They lost 21-10, 21-13 in only 38 minutes.

4:25 p.m.

The Iron Lady is finally taking a break.

Already a two-time swimming gold medalist at the Rio Games, Katinka Hosszu of Hungary dropped the 200-meter butterfly from her program today. She swam each of the first three days of the Olympics and will be in action tonight, going for a third gold in the 200 individual medley.

By dropping the fly, Hosszu gives herself more time to prepare for the IM final. If she had advanced in the 200 fly, she would have had to swim the semifinals at 10:28 p.m. and return

4:10 p.m.

France’s Denis Gargaud Chanut paddled his way to gold at the Rio Olympics, ending a two-man stranglehold in men’s canoe slalom that dated to the 1992 Barcelona Games.

Slovakia’s Michal Martikan and France’s Tony Estanguet had won every gold medal in men’s C1 since the 1996 Atlanta Olympics, but Estanguet retired and Martikan failed to make the Slovakian team.

Gargaud Chanet qualified third and covered the churning course in 94.17 seconds to beat Slovakia’s Matej Benus by 0.85 seconds.

Japan’s Takuya Haneda captured bronze and began weeping in his canoe after the final paddler went past the finish line to secure his medal.

4 p.m.

French Open champion Garbine Muguruza has been upset in the third round of the Olympic tennis tournament by 37th-ranked Monica Puig of Puerto Rico.

Puig routed the third-seeded Spaniard 6-1, 6-1 today.

After beating Serena Williams in the final at Roland Garros for her first major title, the 22-year-old Muguruza lost in the second round at Wimbledon. She had 29 unforced errors to 15 winners today.

The 22-year-old Puig has never been past the fourth round at a Grand Slam.

3:50 p.m.

FAILED TO QUALIFY: In the biggest surprise of the swimming preliminaries, defending Olympic champion Daniel Gyurta of Hungary failed to qualify in the 200-meter breaststroke.

Gyurta’s time of 2 minutes, 11.28 seconds landed him in 17th. He missed out on the last available spot for the 16-man semifinals by two-hundredths of a second. He won gold in the event four years ago in London.

The top qualifier was Anton Chupkov of Russia in 2:07.93. His teammate Ilya Khomenko advanced in fourth.

Americans Kevin Cordes and Josh Prenot also moved on.

3:45 p.m.

Britain has qualified fastest for the men’s 4×200-meter freestyle relay in the Olympic pool.

Stephen Milne, Robbie Renwick, Dan Wallace and Duncan Scott posted a time of 7 minutes, 6.31 seconds in the heats.

The U.S. team of Clark Smith, Jack Conger, Gunnar Bentz and Ryan Lochte was second quickest in 7:06.74. Lochte was competing for the first time in Rio. He figures to return for the nighttime final, joined by three new teammates.

Russia advanced in third in 7:06.81.

3:20 p.m.

Pele hopes to make an appearance at the closing ceremony for the Rio Olympics.

The soccer great, who has been in poor health, tweeted today: “I am continuing my physiotherapy and focused on joining you for the closing festivities on August 21. I love you! #olympics”

Pele was the preferred choice of organizers to light the cauldron during the opening ceremony, but he first said sponsorship commitments and later cited health concerns for keeping him away.

The 75-year-old Pele had hip surgery recently and walks with a cane.

The Olympic cauldron was lit by Brazilian marathon runner Vanderlei de Lima.

3:20 p.m.

Mireia Belmonte Garcia of Spain is the top qualifier in the women’s 200-meter butterfly heats.

Her time of 2 minutes, 6.64 seconds leads 15 other swimmers into the semifinals today night.

U.S. teammates Hali Flickinger and Cammile Adams tied for the second-fastest time of 2:06.67 while swimming in different heats.

Belmonte earned bronze in the 400 individual medley on the first day of the swimming competition.

3:20 p.m.

Penny Taylor turned in the best performance of her Olympic career, scoring 31 points today to help Australia rout France 89-71.

The 35-year-old Taylor, who plays with the Phoenix Mercury and is retiring from women’s basketball after the WNBA season ends, wants to go out a winner.

Taylor opened the second with a 3-pointer and a three-point play to start a 15-0 run to take control and led 46-29 at halftime. The three-time Olympian hit her first seven shots and came off the bench whenever France threatened to trim Australia’s lead under double digits.

It was a big win for the Aussies against the team that beat them in overtime in the 2012 London Games and keeping them from the silver medal.

3:20 p.m.

Defending champions Michael Jung of Germany and Sam FBW won a second successive gold medal in eventing, with another clear round in the showjumping.

Jung, who had picked up no penalties in the cross-country phase or the first jump today, had another perfect round to become only the third rider in Olympic history to win back-to-back individual gold medals.

He is also the only rider to have finished on his dressage score in the Olympics — and already achieved that feat in London, four years ago.

Nicolas Astier and Piaf de B’Neville had four jumping penalties and two time as they added individual silver to the team gold they won with France earlier in the day.

Phillip Dutton of the United States, who had come to within one fence of an individual medal in every major championship since 1994, won bronze on Mighty Nice.

3:15 p.m.

Flip out! Cameroon’s Wilfried Seyi wowed the crowd when he performed a backflip in the middle of the ring following his win in a middleweight bout.

Maybe his next stop should be the Karolyi ranch and a spot on the U.S. gymnastics team.

He had perhaps the best celebration move among the victorious boxers. The boxers like to point to the crowd and dance for what have been wildly enthusiastic crowds.
