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.

Out-of-state crews are headed to Montana to help fight massive fires there as the western part of the country continues to be ravaged by flames and drought.
