Here are our 6 things to watch on Day 4 of the Tokyo Olympics:
1. Simone Biles pulls out of women’s team final after injury
The greatest of all time in gymnastics will not be competing in the remaining events in the women's gymnastics team finals.
Simone Biles appeared to suffer an injury in her first event, the vault. She had an uncharacteristically poor vault, and she failed to stick the landing. After her vault, she could be seen being evaluated by Team USA trainers.
Biles posted the worst score out of the six competitors in the vault with a 13.766. Simone Biles, a vault master, uncharacteristically failed to stick the landing. This comes as a surprise after posting the best score in the vault during the all-around qualifiers. Jordan Chiles had the best score out of the Americans with a 14.666 and Grace McCallum had a 14.300.
Watch the women’s gymnastics team final live on the Olympic channel on Tuesday at 6:45 a.m. ET. You can stream full coverage here or with the Team USA tracker here.
2. Team USA shut out by Japan in softball gold medal game
For the second time in Olympic history, Japan has upset the U.S. in the softball gold medal game.
Team USA, which went undefeated in round-robin play, only had three hits.
The Japanese had a runner in scoring position in each of the first four innings before finally converting on an infield single in the fourth inning.
Japan added a second run in the top of the fifth inning.
3. America wins four medals in swimming, including upset by Alaska native
Most eyes were on Lilly King and Ryan Murphy looking to defend their Olympic crowns Monday night — but a 17-year-old from Alaska stole the show.
American Lydia Jacoby pulled a huge upset over the highly favored Lilly King in the 100m breaststroke. Jacoby won the gold in 1:04.95. King, the defending Olympic champion, was half a second behind, finishing third. Tatjana Schoenmaker of South Africa captured the silver.
While there were four medals earned by Team USA in the pool on Day 4, Jacoby captured the only gold. Murphy finished third in the men’s 100m backstroke, not able to follow up his gold medal in Rio. His time was 52.19.
Regan Smith came in third in the women’s 100m backstroke with a time of 58.05. Kaylee McKeown of Australia won the gold and set a new Olympic record of 57.47 — that after the record was broken in three consecutive heats on Sunday.
The other American, Rhyan White, finished fourth.

4. USWNT wraps up group play with tie against Australia, advances to quarterfinals
The U.S. women’s national soccer team got a much-needed tie against Australia following a stunning defeat against Sweden to begin the tournament.
The USWNT and Australia both had three points in the Group G table through two games. Sweden, with wins over the USWNT and Australia, already clinched one of the two automatic quarterfinal spots.
Two third-place teams will also make it to the quarterfinals, so there is a chance the loser of this match could advance anyways.
The USWNT is looking to return to the podium in Tokyo after missing it for the first time in the event’s history at the Rio Games.
Watch the game on USA Network on Tuesday at 4:00 a.m. ET or stream it live here.
5. A'ja Wilson shines as US Women beat Nigeria, 81-72
It didn't take long for A’ja Wilson to make a splash at the Tokyo Olympics.
The 2020 WNBA MVP scored 19 points to help the U.S. women win their 50th-straight Olympic game, a 81-72 victory over Nigeria.
Despite a slow start in the first quarter, Team USA took over in the second going on a 20-0 run heading into the half.
The U.S. scored 26 points in the third quarter, but Nigeria refused to give up.
Led by Ezinne Kalu, Nigeria went on a 12-0 run to start the fourth but in the end it was Chelsey Gray who stepped up to close out the win for the Americans.
Brittney Griner was the second-leading scorer for the U.S. with 13 points, followed by Diana Taurasi (10), who played in her 33rd career Olympic game.
Brianna Stewart and Sylvia Fowles scored nine points each in the win.
6. Team USA Divers Delaney Schnell and Jessica Parratto Win Silver in Women's 10m Synchronized Platform Diving
Team USA divers Delaney Schnell and Jessica Parratto won silver in the women’s 10m synchronized platform diving competition, the first time the U.S. has medaled in the event.
Parratto returns to the Olympic stage after placing seventh in the event with partner Amy Cozad in Rio. She is joined by Schnell, who secured a bronze medal in the individual 10m platform at the 2019 World Championships.
The pair earned its spot in Tokyo by fending off Katrina Young and Murphy Bromberg at the U.S. Olympic Trials in June.
