Usain Bolt stayed the Fastest Man in the World, doping bickering continued and tennis star Andy Murray made history. In case you missed them, here are some memorable moments from Day 9 of the Rio Games.
The Fastest Man
Jamaica's Bolt, who has not lost an Olympic race since 2008, won the 100 meters on Sunday, the third time in three straight Olympics, in 9.81 seconds.
"I came to this Olympics to win three gold medals. I came to prove myself again as one of the greats and that's my focus," Bolt told reporters after his win.
Despite concerns about how a late start time —10:25 p.m.— might affect his performance, Bolt said that he felt fine once the race began.
"My legs kind of felt dead at the start. But I knew when I got running I'd be fine."
Bolt went up against his U.S. rival, Justin Gatlin, who finished second with a time of 9.89.
Finishing third was Andre De Grasse of Canada in 9.91.
Bolt, 29, won gold in the the 100 meter, 200 meter and 4 X 100-meter relay in both the Beijing and London games.
Gatlin, at 34 the oldest Olympic sprinter in U.S. history, returned to the Olympics after a four-year ban for doping. He won gold in 2004 and bronze in 2012.
"I'm the oldest guy in the field," he said after the race. "So for me to be able to run and just to race and to be able to get on the podium is an honor."
Bolt ran his last two Olympic 100 meter races in 9.69 and 9.63 seconds.
Gatlin has the fastest 100 meter of the 2016 season at 9.80 seconds. Bolt’s fastest time this season had been 9.88 seconds.
Doping Bickering Continues
Russia's top Olympic official called U.S. swimmer Lilly King a "little girl" in a rebuke for her criticism of her Russian rival Yulia Efimova, after the two women clashed over Efimova's doping ban.
Efimova was suspended for 16 months for doping and more recently tested positive for the now-banned substance meldonium.
Their spat began with a finger wagging by Efimova, signaling that she was number one. King did not approve, which she made clear after she beat Efimova for the gold medal in the 100-meter breaststroke on Monday.
"It just proves you can compete clean and still come out on top with all the hard work you put in behind the scenes, behind the meet, at practice and weight sessions," she said. "There is a way to become the best and do it the right way."
Her comment prompted this retort from the head of the Russian Olympic Committee, Alexander Zhukov:
"When athletes start looking like politicians, it's funny, especially when it's a 19-year-old little girl who hasn't achieved anything yet," the Russian Olympic Committee head Alexander Zhukov said in comments reported by R-Sport. "When she grows up, she'll understand she behaved wrongly."
King also criticized the American sprinter, Justin Gatlin, for his doping past when she was asked if it was fair that athletes like Gatlin be allowed to participate.
"Do I think people who have been caught doping should be on the team? They shouldn't. It is unfortunate we have to see that," King said.
Gatlin responded: "I don't even know who Lilly King is."
Gatlin was suspended twice for using performance-enhancing drugs. He was banned in 2001 for a year, and again in 2006 for four years, which kept him from competing at the 2008 Beijing Olympics.
"I've worked hard, all the way from the bottom when I had nothing," Gatlin told The Associated Press. "I worked hard to work back to where I'm at now. I don't understand. The system has worked. I think people need to stop looking at trying to be the judge, the jury and executioner and let the system do its job."
An Olympic Ring
Chinese diver He Zi had just received the silver medal for the 3-meter springboard when fellow diver Qin Kai approached her poolside in front the stadium and -- as the crowd cheered -- got down on one knee and offered an engagement ring. Wiping away tears, she said yes to his proposal and he slipped the ring on her finger.
It was the second public proposal at the Rio Games.
Olympic volunteer Marjorie Edna proposed to her girlfriend -- Brazilian rugby player Isadora Cerullo -- on the pitch last week after a game.
Robbed at Gunpoint
U.S. swimmer Ryan Lochte and three teammates were robbed at gunpoint in Rio de Janeiro overnight Saturday.
"We got pulled over, in the taxi, and these guys came out with a badge, a police badge, no lights, no nothing just a police badge and they pulled us over," Lochte told Today's Billy Bush. "They pulled out their guns, they told the other swimmers to get down on the ground — they got down on the ground. I refused, I was like we didn't do anything wrong, so — I'm not getting down on the ground.
"And then the guy pulled out his gun, he cocked it, put it to my forehead and he said, 'Get down,' and I put my hands up, I was like 'whatever.' He took our money, he took my wallet — he left my cell phone, he left my credentials."
Lochte's comments came after conflicting reports about the robbery. The International Olympic Committee initially denied it took place while his mother was telling news organization that the robbery happened at a party.
Lochte won a gold medal in the 4X200-meter freestyle relay.
Crime has been a worry at the Rio Games. The Portuguese sports minister and Australian coaches were robbed at knifepoint, a Brazilian security officer was shot in the head and killed when he took a wrong turn, and a stray bullet landed in an equestrian press conference.
Olympics Are a Family Affair
Sisters! Two sets ran the Olympic marathon -- twins Anna and Lisa Hahner of Germany, who finished the race holding hands and triplets Leila, Liina and Lily Luik of Estonia, who danced in celebration after the race.
Andy Murray Scores Another First
Britain’s Murray beat Juan Martin del Potro to become the first tennis player in Olympic history to win two singles gold medals.
Murray outlasted del Potro of Argentina over four hours for the victory, taking his second gold in a row.
In 2013, Murray was the first British man to win the Wimbledon Championship in 77 years. He won his second Wimbledon title this year.
Simone Biles Continues to Dominate
The U.S. gymnast Simone Biles won her third Olympic gold medal on Sunday, besting her opponents on the vault.
Biles had already captured the Olympic all-around gold medal and led her team to another gold.
Russian Aliya Mustafina took the gold on the women’s uneven bars.
