Bryson DeChambeau is one of the top pro golfers in the U.S. and now he will miss out at the Tokyo Summer Olympics.

A statement from USA Golf said DeChambeau tested positive for the coronavirus as part of the final protocol before he left the U.S. for Japan. He'll be replaced by Patrick Reed who competed in the 2016 Rio de Janeiro Olympics. Reed will now go through the testing protocol before flying to Tokyo. The men's Olympic golf competition begins Thursday.

TOKYO — An 18-year-old Tunisian managed to pull off a surprise upset in the 400 meter freestyle swimming event, winning the fifth gold medal ever for his country.

Ahmed Hafnaoui erupted in jubilation when he realized he won in the extremely tight race, pumping his fists and placing both hands on his brow as he took in the victory.

He seemed genuinely shocked at the result: "I just can't accept that - it is too incredible."

TOKYO — It's a stunning upset for the world's top-ranked female tennis player. Australia's Ash Barty was a favorite to win gold in women's singles tennis.

But underdog Sara Sorribes Tormo, from Spain, beat her in straight sets in the first round of Olympic competition in Tokyo.

Barty won Wimbledon just two weeks ago.

Sorribes Tormo, 24, is currently ranked 48^th in the world by the WTA tour. She defeated Barty 6-4, 6-3 to go on to the next round in Tokyo.

The U.S. women's soccer team bounced back in a big way Saturday, beating New Zealand 6-1. The win came after a disappointing and surprising loss to Sweden in the Americans' opening match earlier this week.

Skateboarding is ready for its time to shine at the Tokyo Olympics. Competitors will show off the skills they developed in the streets and skateparks around the world, and the hope is that they attract younger fans to watch the Games.

It's been an interesting ride for the sport that has rebel roots in southern California.

The skatepark on the beach in Venice, Calif., is a mecca for the sport. For decades, the area was known as "Dogtown," with skateboarders coming there to show off their skills, doing acrobatic flips and tricks.
