7 p.m.

Yelena Isinbayeva, the pole-vault world record holder, says she is retiring from competing in the sport.

Isinbayeva was prevented from seeking a third Olympic title in Rio de Janeiro after the IAAF banned all but one Russian track and field athlete from the games over their country's state-sponsored doping scandal.

At a news conference in Rio, the 34-year-old Isinbayeva said through a translator that she is "finishing her professional career."

Isinbayeva says she is considering an offer to lead Russia's track and field federation.

Isinbayeva, who has never failed a doping test, was elected as an athletes' representative on the International Olympic Committee on Thursday.

6:30 p.m.

Russia's Gulnaz Gubaydullina has broken the swimming record in women's pentathlon.

Gubaydullina completed the 200-meter race on Friday in 2 minutes, 07.94 records, breaking the record of 2:08.20 by Hungary's Sarolta Kovacs at the 2012 London Games.

Gubaydullina earned 317 points to take a two-point lead over France's Elodi Clouvel after the first of five events at modern pentathlon.

___6:30 p.m.

Russia beat Hungary 19-18 in penalty shots to win bronze in women's water polo.

It's the first medal for Russia in the sport since it took home bronze in 2000.

Russia trailed 12-11 before Anastasia Simanovich scored a power-play goal with one second left in regulation.

The first 13 players connected in the tiebreaker before Anna Karnaukh denied Hungary's Hanna Kisteleki, giving Russia the win.

6:30 p.m.

Germany has defeated New Zealand 2-1 to claim the bronze medal in women's field hockey.

It was Germany's first medal since claiming the gold at the 2004 Games. The Germans lost the semifinal to the Netherlands in a shootout on Wednesday.

New Zealand's fourth-place finish matched its 2012 finish for its best ever.

Friday's match was scoreless at halftime, but Germany's Charlotte Stapenhorst scored 3:26 into the third period, and Lisa Schutze added a goal four minutes later.

New Zealand countered with a goal by Olivia Merry off a penalty corner, but New Zealand could muster just the one goal on eight shots in the second half.

6:10 p.m.

Russia has earned synchronized swimming gold in the team event at the Rio Olympics.

The Russian free routine, performed in angel costumes to the sound of dramatic string music, earned a near-perfect score of 99.1333 for a total of 196.1439.

Russia adds team gold to the duet title won by Natalia Ishchenko and Svetlana Romashina on Tuesday, and has not been beaten in an Olympic synchronized swimming event since 1996. Ishchenko and Romashina also were members of the Russian team Friday and collect their fifth career gold medals.

China took the team event silver with a score of 192.9841, adding it to the silver won in the duet Tuesday. Japan scored 189.2056 to beat Ukraine to bronze and secure its first synchronized swimming team medal since 2004.

5:35 p.m.

Carolina Marin of Spain has beaten P.V. Sindhu of India to take gold in women's singles badminton.

Her victory Friday signals a clear end to China's previous lock on Olympic badminton power. Marin fell face first on the court, then kneeled and wept after her 2-1 victory.

Marin, the world No. 1 and the favorite ahead of Rio, beat Li Xuerui, the defending Olympic champion from China, to get to the gold medal match.

In men's singles Lee Chong Wei of Malaysia earlier overcame two-time Olympic champion Lin Dan of China to advance to the finals against a younger Chinese star, Chen Long.

Sindhu, ranked world No. 10, made a strong run through the tournament, overpowering higher-ranked Nozomi Okuhara of Japan in the semifinals. Her silver medal makes up somewhat for the disappointing run of fellow Indian Saina Nehwal, who took bronze in London but crashed out of the Rio Games early.

Marin cruised to an early lead in the first game, displaying her superior experience by repeatedly rushing the net and slamming winners back toward an often befuddled Sindhu. But the Indian settled down, chasing down smashes and drop shots and rallying to tie the game at 19. Then, in rapid succession, she took two points to stun the Spaniard, 21-19.

The second game saw an aggressive Marin win 21-12. In the deciding game Sindhu came back from a deficit and tied the match at 10 after a long, exciting rally that saw repeated smashes and several lunging saves. But Marin opened another lead and Sindhu couldn't come back, losing 21-15.

5:35 p.m.

A weightlifter from Kyrgyzstan who was the first athlete to be stripped of a Rio Olympics medal because of doping is planning an appeal.

Izzat Artykov tested positive for strychnine, a pesticide which can be used as a stimulant in small doses, after winning bronze in the men's 69-kilogram category at the Olympics last week, and was stripped of his medal Thursday.

The Kyrgyz government's State Sports and Fitness Committee says in a statement Friday that sports officials in the country are drafting an appeal against the Court of Arbitration for Sport's ruling to disqualify Artykov.

The committee has not specified the grounds for the appeal, but says it is demanding the World Anti-Doping Agency conduct repeat tests of Artykov's sample.

U.S. swimmer Ryan Lochte issued an apology Friday morning about an incident that occurred early Sunday at the Rio Olympics. Lochte initially said he and three teammates had been robbed at gunpoint, but Rio police discounted that on Thursday and instead said the swimmers vandalized a gas station bathroom and then paid some guards before leaving. Following is the full text of Lochte's statement, posted to his Instagram account.

I want to apologize for my behavior last weekend - for not being more careful and candid in how I described the events of that early morning and for my role in taking the focus away from the many athletes fulfilling their dreams of participating in the Olympics. I waited to share these thoughts until it was confirmed that the legal situation was addressed and it was clear that my teammates would be arriving home safely.

It's traumatic to be out late with your friends in a foreign country - with a language barrier - and have a stranger point a gun at you and demand money to let you leave, but regardless of the behavior of anyone else that night, I should have been much more responsible in how I handled myself and for that am sorry to my teammates, my fans, my fellow competitors, my sponsors, and the hosts of this great event. I am very proud to represent my country in Olympic competition and this was a situation that could and should have been avoided. I accept responsibility for my role in this happening and have learned some valuable lessons.

I am grateful for my USA Swimming teammates and the USOC, and appreciate all of the efforts of the IOC, the Rio '16 Host Committee, and the people of Brazil who welcomed us to Rio and worked so hard to make sure that these Olympic Games provided a lifetime of great new memories. There has already been too much said and too many valuable resources dedicated to what happened last weekend, so I hope we spend our time celebrating the great stories and performances of these Games and look ahead to celebrating future successes.

4:10 p.m.

Drama, yes, drama, in the men's 50-kilometer walk at the Rio Games, with world record holder Yohann Diniz keeling over after 35K, stricken by apparent stomach problems having built up a commanding early lead.

Officials helped the gritty high-school sports coach from France back to his feet. He doused his head with a bottle of water and was off again, but is struggling and has dropped back.

Evan Dunfee of Canada is now in a five-man lead group, along with reigning Olympic champion Jared Tallent of Australia and world champion Matej Toth from Slovakia, that is in medal-contention in the longest athletics event of the games.

3:15 p.m.

Malaysia's Lee Chong Wei has beaten two-time Olympic champion Lin Dan of China in Olympic Badminton, avenging his last two losses to Lin in the Olympic finals.

Both men are considered by many to be the best players of their era, and maybe of all time, and Friday's semifinal match was often thrilling.

Lee's reaction at the end — falling to his knees, covering his face with his hands and putting his forehead on the court before leaping up in the air and pumping his fists — made it seem more like a gold medal contest than the semifinals.

Lin jumped out to a commanding early lead in the first game of the best-of-three match, and fended off a Lee rally to win 21-15. Lee, his nerves settled, came out fast in the second game and won 21-11. The deciding game was much closer, with the lead swinging back and forth. Lee stretched out a small lead toward the end and was on the brink of winning, but Lin charged back, fighting off several match points to tie the game at 20. Lin then pulled away to win 22-20.

Lee, who served an eight month doping ban, is looking for an Olympic championship to ease the heartbreak of the two previous final-match losses to Lin.

Standing in the way will be two young powers: China's Chen Long plays Viktor Axelsen of Denmark in the other semifinal match Friday.

Later Friday the women's singles gold medal match will be decided, as Spain's Carolina Marin, the world No. 1, plays surprise finalist P.V. Sindhu of India.

Malaysia and China will also play in the men's doubles gold medal match.

12 p.m.

Usain Bolt says this will be his final Olympic race.

(Michael Phelps said that too once, but that's a whole 'nuther story.)

The astonishing sprinter is back on the track Friday, looking to add to his medal stash as part of the Jamaican team in the 4x100 relay. Bolt and Jamaica won the event at the Beijing and London Olympics, where the team set the world and Olympic records.

So far, there's only one opponent that can really beat Bolt - and that's time.

Bolt romped in the 200 meters Thursday night, but finished in 19.78 seconds, .59 short of his own world record. Still, that gave him Olympic gold medal No. 8 and a third straight 200 title to go with the same trifecta in the 100 meters.

As for his Rio Olympic goals, Bolt said immortality was the main one.

"What else can I do to the world to prove I am the greatest? I'm trying to be one of the greatest. Be among Ali and Pele," Bolt said.

11:25 a.m.

The lawyer for U.S. Olympic swimmer James Feigen says he will pay about $10,800 Friday and then leave Brazil following the robbery scandal involving the U.S. swim team.

Attorney Breno Melaragno says early Friday that, under an agreement reached with a Brazilian judge, Feigen will donate 35,000 Brazilian reals to an "institution" and depart.

Melaragno did not specify where the money will go, but the term "institution" can be taken to mean charity. The lawyer said under Brazilian law, a donation can be made to avoid criminal prosecution for minor offenses, but did not say what charge was being contemplated against Feigen.

Feigen's teammates Gunnar Bentz and Jack Conger left Brazil on Thursday night after giving testimony to police.

Police say U.S. swimmer Ryan Lochte and the three others had not been held at gunpoint, as Lochte initially claimed. Instead, Brazilian police say the U.S. athletes were intoxicated, vandalized a bathroom, then were questioned by armed guards before they paid for the damage and left.

10:45 a.m.

Spain was always going to be in the way of the U.S. men's basketball team at the Rio Olympics - whether it was playing for the gold medal, as they had in the last two Olympics, or just for the chance to get into the gold medal round.

Spain gets another chance Friday to knock off the U.S. men after being oh-so-close in the 2012 and 2008 Olympics.

"It would mean everything for us," says Spanish point guard Ricky Rubio. "I remember watching Argentina beat the U.S. in 2004, and I think maybe the same story that Argentina wrote with the 'Gold Generation,' we can write, too."

In the other semifinal, Australia plays Serbia. Both teams came close in their games against the U.S. as the favorites have shown some vulnerability in Rio.

10:20 a.m.

Germany had better hope that the women's Olympic soccer final Friday against Sweden doesn't come down to penalty kicks.

The Swedish team is getting a reputation as a giant-killer in Rio. While many figured that the World Cup champion U.S. team would be cruising to its fourth straight Olympic gold, Sweden beat them on penalty kicks.

With the U.S. out, many thought host Brazil and its star Marta would surely be playing for gold - but Sweden knocked them off on penalty kicks.

Neither Sweden nor Germany have never played before in a women's Olympic soccer final but their coaches have known each other for decades. Germany's Silvia Neid, who is stepping aside after this Olympic final, and Sweden coach Pia Sundhage were both in the first women's Olympic soccer tournament in 1996.

Canada and Brazil face off earlier Friday for the bronze medal.

9 a.m.

Brazilians adore the beach and the water - so nothing could be better for the Olympic host than picking up its latest two golds at those venues.

The men's volleyball team of Alison and Bruno set off a boisterous celebration in the rain on Rio's Copacabana Beach when they won, and had to hold back tears as compatriots belted out the national anthem next to the crashing surf.

"In front of our people. In the best spot for this sport," Bruno said. "This is a magical feeling."

After snatching away the gold with a dramatic finish in the women's 49erFX, sailors Martine Grael and Kahena Kunze hugged, then flipped backward off their boat into Guanabara Bay. Family and friends jumped into the surf to celebrate, then carried the sailors' boat up to the beach with the women still standing in it.

"It's actually how I hoped I could be taken out of the water," Grael said.
