Tokyo Olympics while you were sleeping: Simone Biles withdraws, Naomi Osaka ousted

The Tokyo Olympics' biggest stunner emerged as the East Coast was just waking up: star Simone Biles withdrew from the gymnastics team final because of a medical issue. She will not be competing in the remaining events and will be assessed further to determine availability for future competitions in Tokyo, a USA Gymnastics spokesperson told USA TODAY.

Overnight, Naomi Osaka was knocked out of the women's tennis tournament on Tuesday. 

This was no fluke: The Czech Republic's Marketa Vondrousova won 6-1, 6-4 and was the better player throughout their third-round matchup. 

From NFL plays to college sports scores, all the top sports news you need to know every day.

Osaka had dominated her first two matches, but she made 32 unforced errors in suffering a rare loss on hard courts. After lighting the Olympic cauldron, her dream of winning the gold medal in her home country is now dashed. 

The women's tennis tournament as a whole is wide-open, too. Osaka seemed like the clear-cut favorite after No. 1 Ash Barty and No. 3 Aryna Sabalenka were also bounced early.

Here are some of the other notable things you missed Tuesday in Tokyo while you were sleeping:  

Carissa Moore makes history with surfing gold

American surfer Carissa Moore made history Tuesday by securing the gold medal in the first-ever Olympic surfing competition. 

Moore, a four-time world champion, won the women's final over South Africa's Bianca Buitendag, 14.93-8.46. 

Moore, 28, beat Brazil's Silvana Lima in the quarterfinals and then fended off Japan's Amuro Tsuzuki in the semifinals earlier in the day.

Another strong day in the pool 

It was a solid day in the pool for Team USA's swimmers and divers as they picked up five medals, including one gold.

Lydia Jacoby's upset win in the women's 100-meter breaststroke was the highlight of the day – well, maybe the second-best highlight behind her small Alaska hometown's incredible celebration of her gold.  

U.S. teammate Lilly King took bronze in the 100 breast behind Jacoby. Team USA's other swimming medalists Tuesday were Regan Smith, who claimed bronze in the women's 100 backstroke, and Ryan Murphy, who captured bronze in the men's 100 backstroke.

Team USA also got a breakthrough medal from divers Delaney Schnell and Jessica Parratto. The duo took silver in the women's synchronized 10-meter platform, an Olympic event the United States had never placed top-three in before. 

U.S. women's hoops team wins but is far from dominant 

The United States women's basketball team kicked off action in Tokyo with an 81-72 win over Nigeria. 

It was the 50th consecutive Olympic victory for Team USA, but just the second in that stretch in which the margin was fewer than 10 points. The U.S. was never quite able to put Nigeria away and was sloppy with the ball.

Simply put: There's things to clean up, and a run to the gold medal will not be easy this time, Dan Wolken writes. 

USWNT moving on to knockout rounds

It wasn't always pretty, but the U.S. women's soccer team is moving on to the knockout rounds.

The USWNT played Australia to a 0-0 draw Tuesday in their final group game, securing second place in Group G and setting up a quarterfinal matchup against either Brazil or the Netherlands.

Alex Morgan appeared to score the game's only goal in the first half, but it was called offside and that ruling held up on review.
