Day 6 in Rio saw Simone Biles outshine everyone to take the individual gold in woman's gymnastics, while Michael Phelps defeated his longtime rival, Simone Manuel made history in the pool, golf returned with a bang and Fiji finally won a gold. The day's top moments at the Summer Games are here, in case you missed them.
Simone Biles Takes Individual Gold
Simone Biles won the gold medal in the women's gymnastics individual all-around event, with commanding performances in her two best events, balance beam and the floor exercise. It was the U.S. gymnastics team's second gold medal at the Rio Olympics and the Americans' fourth straight victory in the event. Aly Raisman took the silver with a strong balance beam routine and floor exercise. Russia’s Aliya Mustafina took the bronze.
The 19-year-old Biles — who joins the ranks of such American winners as Mary Lou Retton and her teammate Gabby Douglas — and Raisman, the 22-year-old team captain, were expected to finish on top.
After the results were announced, Biles, who dominates the sport, invited Raisman out before the crowd to share the applause and an emotional embrace.
Biles will compete again on Sunday in the women’s beam and vault finals, while Raisman will compete in the floor finals.
The Americans, now known as the "Final Five," won the team gold on Tuesday. Their team is the last to have five members. Beginning with the Toyko Games in 2020, the gymnastics teams will have only four competitors.

"One Last Time"
U.S. swimming superstar Michael Phelps won his 22nd gold medal Thursday in the 200-meter individual medley, defeating his longtime rival and teammate, Ryan Lochte.
The two are not always rivals. They won gold together in Olympic relay events, including the men's 4x200m freestyle relay Tuesday evening in Rio.
Their 12-year rivalry has evolved into a competitive friendship, and the two are even roommates in Rio.
This was most likely the last showdown between the two, because Phelps said that he plans to retire after Rio, his fifth Olympic Games.
More Swimming History
American Simone Manuel became the first African-American woman to win a gold medal in swimming. She tied Canada's Penny Oleksiak for the gold in the 100-meter freestyle in an Olympic record time of 52.70 seconds.
Golf Returns to the Olympics
It was an ace 112 years in the making.
On Thursday, golf was part of the Olympic Games for the first time since 1904, and Great Britain's Justin Rose celebrated its return with a hole-in-one. The first ace of the 2016 Rio Olympics, it came on the par-3 fourth hole during the first round of men's golf.
Rose, who was one of the favorites coming in to the tournament, finished the day with a four-under-par 67 and tied for fourth.
The golfers are sharing the grassy course with giant hamster-like rodents.
The capybara, which is native to South America, is the world's largest rodent. A close relative to the guinea pig, it is known to grow to more 4 feet in length but is not dangerous.
Far from being fazed, the golfers have taken to posting pictures of the furry rodents online.
In 1904, only the United States and Canada competed — and a Canadian won the individual gold. This year, despite the excitement of the sport's return, some of the world's top players gave the Games a pass, citing golf's crowded schedule of championships and other concerns. Golf will be played again in 2020 in Tokyo but its fate after that is uncertain. A vote will be held next year to decide if it will be back in 2024.
Fiji Wins First Gold
Another returning sport, rugby, gave Fiji its first ever gold medal.
The country's rugby sevens squad drubbed Great Britain to secure the win.
Rugby returned to the Olympics this year after a more than 90-year absence. The last time the sport was played at the Summer Games, in 1924, it was the 15-side version.
Even security forces aren't immune to crime in Rio.
Officers from Brazil's national security force were using a GPS to navigate unfamiliar streets when they took a wrong turn and came under fire. One officer was shot in the head, underwent a four-hour surgery and was in stable condition, according to the Justice Ministry.
The shooting was the latest in a string of robberies and attacks that have marred South America's first Olympic Games. Homicides in Brazil had declined in past years but spiked as the country experienced its worst recession in decades.
Two Australian rowing coaches were robbed at knifepoint over the weekend near Ipanema Beach. Portugal's sports minister was robbed, at the Olympic Lake, though his money was recovered.
The equestrian venue was hit twice by stray gunfire. A judo medalist from Belgium was punched in the face on Copacabana beach when he chased a thief.
Ledecky Sets Another Record
U.S. swimmer Katie Ledecky broke another Olympic record Thursday.
Ledecky, 19, set the new record with the fastest time in the 800-meter freestyle preliminaries.
Her time: 8 minutes, 12.86 seconds.
Ledecky has won three gold medals in Rio. She anchored the U.S. women's swimming team in the 4 x 200-meter freestyle relay for the third Wednesday night.
She is hoping to sweep the 200-meter, 400-meter and 800-meter freestyle events -- which last happened in 1968 at the Mexico City Games.
She swims the 800 meters on Friday.
Kayla Harrison became the first American to defend an Olympic judo title on Thursday, beating France's Audrey Tcheumeo in the final of the 78-kg competition.
Harrison won the U.S.'s first judo gold in London in 2012, and she is only the second American to take two Olympic judo medals. The second is her coach, Jimmy Pedro, who twice won bronze medals.
Harrison was sexually abused by a previous judo coach, who was later sent to prison. She credits training under Pedro with helping her to recover.
