Sunisa Lee stepped up in the absence of Simone Biles to claim gold and maintain Team USA’s dominance in the women's gymnastics all-around event.
The 18-year-old became the sixth American woman to take the title – and fifth in a row – after beating Brazil's Rebeca Andrade and Angelina Melnikova to gold.
Despite withdrawing from the final to focus on her mental health, Biles was cheering on from the stands as her team-mate aimed to capitalise.
Lee was looking to continue her nation's impressive record in this event, which has seen triumph concurrently at both the Olympic Games and World Championships since 2010.
The teenager admitted she came close to quitting gymnastics following a difficult two years – both in and out of the gym.
Nevertheless, she duly delivered the goods by totalling 57.433 to take gold and edge out Andrade, who became the first Brazilian woman to claim an Olympic medal in artistic gymnastics.
"It feels crazy, it is so surreal. It's a dream come true," Lee said. "I don't even know what to say. It hasn't even sunk in. The past two years with COVID have been crazy. There was one point I wanted to quit.
"To be here and to be an Olympic gold medallist is just crazy."
PATIENT FOX COMES GOOD
Australia's Jess Fox became the first women's canoe slalom (C1) Olympic gold medallist.
A multiple World champion, Olympic gold has eluded Fox over the years. She was a silver medallist at London in 2012, while she took home a bronze from Rio four years later.
However, her persistence finally paid off after posting a time of 105.04 seconds in the final, while Great Britain's Mallory Franklin and Andrea Herzog of Germany completed the podium.
"I can't believe it," said Fox, who also won bronze in the women's kayak earlier this week.
"I was dreaming of [a gold medal] and I really believed it was within me, but you never know what is going to happen at the Olympics.
"It is about holding your nerve and I probably didn't do that very well in the kayak a couple of days before, so it was hard to get to this point. But it has been incredible to do what I did today."
