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

11:05 p.m.

The Olympic tennis men’s doubles semifinals are set, and among those closing in on a medal are Rafael Nadal and Marc Lopez of Spain, and Steve Johnson and Jack Sock of the United States.

Johnson and Sock advanced Tuesday by beating the eighth-seeded duo of Roberto Bautista Agut and David Ferrer of Spain 6-4, 6-2.

10:15 p.m.:

Defending Olympic champion Nathan Adrian barely advanced in the preliminaries of the 100-meter freestyle at the Rio Olympics.

He wasn’t taking any chances in the semifinals Tuesday night.

Competing in lane eight, Adrian posted the fastest time out of 16 swimmers, sending him to Wednesday’s final with a much more customary position in the center of the pool.

The biggest cheers at the Olympic Aquatic Center were for Brazil’s Marcelo Chierighini, who advanced to the final with the eighth-best time.

9:25 p.m.:

With time running out, Catalina Usme beat Hope Solo with a free kick from a tight angle to give Colombia a 2-2 draw against the United States on Tuesday at the Olympics.

Usme also scored in the 26th minute to give the Colombians an early 1-0 lead. It was the team’s first-ever Olympic goal, and first-ever goal against the United States.

Despite the draw, the top-ranked United States still finished atop Group F.

Teenager Mallory Pugh became the youngest player to score for the United States in an Olympics with her goal in the 59th minute, giving the Americans a 2-1 lead. Crystal Dunn also scored for the defending champions.

The U.S. women’s team, the reigning World Cup champions, is vying for its fourth straight Olympic gold medal.

8:05 p.m.

UPSET ALERT: Defending champion Serena Williams is out of the Rio de Janeiro Olympics after a stunning loss in the third round of singles.

The No. 1-seeded American was beaten 6-4, 6-3 on Tuesday night by Elina Svitolina of Ukraine.

Williams made 37 unforced errors, including eight double-faults – five in one game.

She entered the night with a 4-0 record against Svitolina.

But all those mistakes added up, and now the 2012 London gold medalist in singles and doubles is finished in Rio.

She and her sister, Venus, lost in the first round of doubles.

8 p.m.

Colombia scored its first-ever Olympic goal against the United States in the 26th minute Tuesday night in Manaus and the teams were tied at halftime.

Catalina Usme’s free kick went around the wall and bounced between Hope Solo’s legs to give Colombia an early lead.

Crystal Dunn scored the equalizer for the Americans in the 41st minute and the match was knotted at 1 at the break.

The match marked the return of midfielder Megan Rapinoe, who had ACL surgery last December. Rapine was replaced in the 33rd minute by teenager Mallory Pugh. Temperatures at the Amazonia Arena in Manaus were in the upper 80s.

7:20 p.m.

The Belgian Olympic committee says judo competitor Dirk Van Tichelt was hit in the face during celebrations of his bronze medal performance on Copacabana beach.

It said that his phone was stolen late Monday on the popular strip and that he was hit as he was chasing the local thief.

Van Tichelt was taken to hospital for observation but needed no further treatment. He appeared with a black eye at a media event on Tuesday.

7 p.m.

Megan Rapinoe was in the starting lineup for the United States on Tuesday night against Colombia at the Olympic.

The winger tore her right ACL during a training session in Hawaii before a scheduled World Cup victory tour match last December and required surgery. She hasn’t played in a competitive match since October.

Rapinoe, who helped the United States win the gold at the 2012 London Games and clinch the World Cup title last year in Canada, has looked fit during warmups since the team arrived in Brazil.

The start for Rapinoe was one of several changes U.S. coach Jill Ellis made to the lineup for the match in Manaus. With victories in the first two matches, the Americans were already assured a spot in the quarterfinals.

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

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 Tuesday 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 on Tuesday 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.

South Korean Sangyoung Park stormed back to score the final five points and take gold in men’s epee Tuesday 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.

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 on Tuesday.

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 on Tuesday, 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.

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 on Tuesday, 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.

It’s another Olympic diving gold for the Chinese.

Chen Ruolin and Liu Huixia won the women’s 10-meter synchronized platform title Tuesday, 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 on Tuesday. 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. On Tuesday, 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 Tuesday.

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 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.
