The Latest: Del Potro in quarters after come from behind win

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

1:35 p.m.

Juan Martin del Potro got an extra day of rest then a come-from-behind three-set win to reach the quarterfinals of the Olympic tennis tournament.

The 2009 U.S. Open champ stunned top-ranked Novak Djokovic in the first round Sunday, part of nearly 7 hours on court between singles and doubles in a span of about 25 hours. Then his third-round match Wednesday got rained out, and he looked strong in the final set in beating 117th-ranked Taro Daniel 6-7 (4), 6-1, 6-2 on Thursday in 2 hours, 12 minutes.

Del Potro’s ranking is actually worse than Daniel’s — 141st in the world — as he’s coming back from three left wrist surgeries. The Argentine isn’t sure his conditioning can hold up long enough to win his second Olympic singles medal to go with his bronze from 2012.


1:20 p.m.

Rafael Nadal is into the quarterfinals at the Olympics in his first tournament in 2½ months.

The 14-time major champion beat 15th-seeded Gilles Simon of France 7-6 (5), 6-3 in a match delayed a day by rain. He also plays doubles and mixed doubles later Thursday.

The 2008 gold medalist withdrew from the French Open because of an injured left wrist and has said he wouldn’t be playing this week if it weren’t the Olympics. Nadal was supposed to be Spain’s flag bearer in 2012 but missed the London Games because of a bad knee.

He finally led out the delegation at last Friday’s opening ceremony. In his toughest test of his three singles matches so far, Nadal had 28 unforced errors in the first set but just 12 in the second.


1:20 p.m.

The coach of Russia’s lone Olympic track and field athlete tells The Associated Press there’s no need for her to take on the entire world on her own.

Long jumper Darya Klishina will open her Olympic stay next Tuesday.

She was the only Russian cleared to compete after track’s governing body suspended the team for the Olympics because of widespread doping within the program. Klishina got clearance because she lives and trains in Florida and all her drug testing has taken place there.

Her coach, Loren Seagrave, says Klishina is well aware of the situation but she’s focusing on herself, not the politics surrounding her presence in Rio. Says Seagrave: “She’s real good at being Darya Klishina, and not taking on the entire world on her own.”


1:05 p.m.

It’s been a good start to the day for the U.S. Olympic team at tennis: Madison Keys is into the women’s semifinals, and Steve Johnson is into the men’s quarterfinals.

Keys, who is seeded No. 7, beat Daria Katsanika of Russia 6-3, 6-1 in 53 minutes Thursday, thanks in large part to a 30-4 edge in winners. One more victory, and Keys will be assured of going home with a medal.

Johnson, seeded No. 12, had a similarly easy time of it against Evgeny Donskoy of Russia, winning 6-1, 6-1.

They’re the last two Americans in singles play at the tennis. The other six lost early, including Venus Williams in the first round, and Serena Williams in the third.


1:05 p.m.

Defending Olympic judo champion Kayla Harrison is through to the semifinals of the women’s 78-kilogram division at the Rio de Janeiro Olympics.

Her first bout lasted just 43 seconds. She next faces seventh-ranked Slovenian judoka Anamari Velensek in the semifinal later Thursday. If Harrison advances to the final, she will be guaranteed at least a silver.

Harrison, the first American to win a judo gold medal, looked completely focused on the mat Thursday. She won both her preliminary matches by pinning her opponents to the mat for 20 seconds.

Harrison’s main rival, Brazilian Mayra Aguiar, also advanced. The partisan crowd loudly booed Harrison as she entered and left the stadium, but the American has said she isn’t bothered by the cheers for her opponent and is simply driven to fight harder.


1:05 p.m.

Shiva Thapa was easily identifiable as an Indian boxer with his country’s designation on the back of his vest.

The first two Indian fighters in the tournament did not have IND on the back of the fighting vests.

The International Boxing Association (AIBA) asked for the country name to be placed on the vests. Wearing a vest with the country’s designation is required in Olympic boxing.

An AIBA spokesman said Indian fighters would have worn neutral vests had the problem not been resolved. There was never a threat of Olympic expulsion.


12:40 p.m.

Sailing’s governing body says Evi van Acker of Belgium reported feeling ill after competing in the Laser Radial class on polluted Guanabara Bay.

World Sailing spokesman Darryl Seibel says van Acker, the bronze medalist at London, was evaluated by the chief medical officer after her races on Wednesday, and then evaluated further by medical officials from the Belgian team that night.

It’s not immediately clear whether the illness is because of the polluted water.

Seibel said Thursday that this appears to be an isolated case and van Acker is the only sailor who has reported feeling ill in the opening days of the regatta.

Van Acker, a favorite to return to the podium in Rio, has had consistently worse performances. She was second and 12th on Monday, second and 29th Tuesday and then 16th and 15th in tough conditions on Wednesday.

An independent study by The Associated Press has shown high levels of viruses and sometimes bacteria from human sewage in the water.


12:25 p.m.

The men’s table tennis final is set and there’s little surprise that it’s another all-China affair.

World No. 1 Ma Long will face London champion Zhang Jike later Thursday.

It guarantees that Rio will be the third straight Olympics where Chinese men will take both gold and silver.

Ma beat Japan’s Jun Mizutani four games to two in the first best-of-seven-game semifinal match.

Early on, Ma managed to look both relaxed and overwhelmingly strong, smashing forehand after forehand at Mizutani and frequently forcing the Japanese man into errors. Mizutani put up a fight toward the end, winning the fourth and fifth games, but Ma was too strong in the sixth game.

In the other semifinal, Zhang, whose first name was inspired by Brazilian soccer star Zico, beat Vladimir Samsonov, a 40-year-old from Belarus and former world No. 1, 4-1.

Zhang has had erratic performances since his London victory, and there are two Chinese men ranked ahead of him internationally, but he also has a reputation for showing up for big matches.

Zhang won the first three games, each by only two points. Samsonov took the fourth game, using his size advantage to send backhand winners down the edges of the table at steep angles. But Zhang narrowly won the fifth game to reach the finals.

Samsonov will face Mizutani in the bronze medal match later Thursday.


12:10 p.m.

Switzerland has won the lightweight men’s four in the final medal race of the day at the rowing regatta.

The Swiss four crossed the line in 6 minutes, 20.51 seconds, with Denmark getting the silver medal and France the bronze.

Six medal races were completed on the Rodrigo de Freitas Lagoon on Thursday after Wednesday’s races were canceled due to windy conditions.


11:50 a.m.

Brothers Martin and Valent Sinkovic clinched Croatia’s first Olympic gold medal in rowing on Thursday by winning the men’s double sculls.

The double world champions persevered in a tight race against Lithuanians Mindaugas Griskonis and Saulius Ritter.

The Croatians are the third sibling pair to win Olympic gold in either the men’s or women’s double sculls.

Kjetil Borch and Olaf Tufte finished third to collect Norway’s first medal at the Rio Olympics.


11:40 a.m.

Rower Katherine Grainger has become Britain’s most decorated female Olympian after winning a silver medal in the women’s double sculls.

Grainger, competing in her fifth straight Olympics, and Victoria Thornley were beaten to the finish line by Poland’s Magdalena Fularczyk-Kozlowska and Natalia Madaj. Lithuania got the bronze.

Grainger won a gold medal in London four years ago and silver medals in Sydney, Athens and Beijing. She is the only British woman with five Olympic medals.


11:30 a.m.

Defending Olympic judo champion Kayla Harrison is off to a speedy start at the Rio de Janeiro games on Thursday; the American defeated her first-round opponent in just 43 seconds.

Facing off against China’s Zhehui Zhang, Harrison immediately took hold of Zhang’s uniform and wrestled her to the ground. After holding her down for 20 seconds, Harrison won with an automatic ippon victory.

Just minutes before her match, however, Harrison’s biggest rival, Brazilian Mayra Aguiar, had an even quicker first-round match. Aguiar threw her opponent, Australia’s Miranda Giambelli for a match-winning throw in just 39 seconds, to roars of “Mayra” from the mostly Brazilian crowd.

Top-ranked Harrison and world number four Aguiar are expected to meet in the final later in the afternoon. Harrison holds a slight nine to eight lead in their previous encounters, but Aguiar will have the home-crowd advantage. Upon Harrison’s entrance onto the judo mat, she was boisterously booed in the stadium.


11:05 a.m.


New Zealand rowers Eric Murray and Hamish Bond have defended their Olympic gold and extended their winning streak in the men’s pair.

The six-time world champions, who are undefeated since they first started competing in the event in 2009, finished more than a boat-length ahead of silver medalist South Africa. Italy’s pair placed third.

In the first medal race of the Rio regatta, defending Olympic champion Germany held off Australia at the finish line to win gold in the men’s quadruple sculls. Estonia got the bronze.

Germany also won the women’s quadruple sculls thanks to a late surge that pushed the German boat past Poland, which had led the race from the start.

The Netherlands also sprinted past the fading Poles, who had to settle for bronze. The United States, world champion in the event last year, finished in fifth place.


10:20 a.m.

Large posters with the image of Kuwaiti shooter Fehaid al-Deihani clasping his gold medal hang in one of Kuwait’s most popular malls and government officials are praising his win in Rio, despite not playing for the Kuwaiti flag.

Kuwaiti athletes are not competing under their national flag this year due to a suspension by the International Olympic Committee, which deemed certain provisions in the country’s sports legislation as government interference in Olympic autonomy.

The state-run Kuwait News Agency Thursday quoted officials saying al-Deihani’s win in double-trap demonstrates the capabilities of Kuwaiti athletes in the face of “hardships.”

Minister of State for Youth Affairs Sheikh Salman Al-Sabah said despite Kuwait’s suspension from the games, Kuwaiti athletes insisted on competing under the Olympic flag to prove “they are able to represent their country.”
