The stars were out Sunday in Rio de Janeiro, as Simone Biles and Usain Bolt were among the biggest names in action at the 2016 Summer Olympics.
Biles had already claimed gold in the individual and team all-around events, and the 19-year-old headed to the vault hoping to add a third gold medal.
Bolt was the two-time reigning champion in the men's 100-meter dash and hoped to capture an unprecedented third title in the event.
With another week left at the 2016 Olympics, the United States owns a sizable lead over China in the overall medal count:
Below is a look at the results from each of Sunday's medal events and a brief recap for how the day's action unfolded.

Bolt made it a hat trick after defeating Justin Gatlin by 0.08 seconds in the 100-meter dash. His final time (9.81 seconds) was the slowest of his three Olympic wins—9.69 seconds in 2008 and 9.63 in 2012—but he was more than equipped to beat the best competition in the world.
Bolt still had enough time to start his celebration before crossing the finish line, which NBC Olympics shared on Twitter:
Cleveland Cavaliers forward Tristan Thompson was among the many who were praising the Jamaican sprinter:
Bolt is also set to compete in the 200 meters and 4x100-meter team relay.
"Somebody said I can become immortal," he said, per USA Today's Paul Myerberg. "Two more medals to go and I can sign off. Immortal."
Like Bolt, Biles lived up to the hype and earned a dominant win in the women's vault. NBC Sports' Nick Zaccardi put her margin of victory over Russia's Aliya Mustafina into perspective:
NBC Sports uploaded a replay of her second jump:
Biles is a perfect 3-of-3 in Rio, with the balance beam and floor exercise still to come. She'll be the heavy favorite to win both events, and if she walks away from Brazil with five golds, Biles will be able to make a case that she's the greatest female gymnast ever.
Rather than Biles or Bolt, though, Wayde van Niekerk may have put together Sunday's most dominant performance. The 24-year-old South African won the men's 400 meters with a time of 43.03 seconds, smashing the world record (43.18 seconds) Michael Johnson set in 1999.
Van Niekerk, who ran from Lane 8, led for most of the race and managed to pull away from Kirani James and LaShawn Merritt in the final 100 meters:
Johnson was gracious after seeing his record go down:
"I believed I could get the world record. I've dreamed of this medal forever," Van Niekerk said, per the Guardian's Ian Prior. "I am blessed."
Max Whitlock made history for Great Britain, bringing the team its first-ever gold medal in gymnastics. He began the day by winning the men's floor exercise. Later Sunday, Whitlock doubled his medal haul, winning gold on the pommel horse.
Nine sports will hand out medals Monday. The men's 800-meter and women's 400-meter finals are two of the most heavily anticipated events, while Biles will look to continue her hot streak on the balance beam.
With time rapidly running out on the 2016 Olympics in Rio, fans should squeeze in as much as they can over the next few days before the party packs up and departs Brazil.
