Coach Laurent Landi embraces Simone Biles, after she exited the team final with apparent injury, at the 2020 Summer Olympics, Tuesday in Tokyo. The 24-year-old reigning Olympic gymnastics champion Biles huddled with a trainer after landing her vault. She then exited the competition floor with the team doctor.

TOKYO (AP) — Simone Biles came into the Olympics as perhaps the biggest star of the Games. Naomi Osaka was such a big headline act that she was given the honor to light the Olympic flame in her native country.

In a matter of just hours on Tuesday, Osaka was knocked out early from the Olympic tennis tournament and Biles pulled out of the gymnastics team competition when she realized following a shaky vault she wasn’t in the right headspace to compete.

“I didn’t want to go into any of the other events second-guessing myself,” Biles said. “So I thought it would be better if I took a step back and let these girls go out there and do their job.”

The team representing the Russia Olympic Committee surged past the short-handed U.S. to the top of the podium, posting a score of 169.258 to win the country’s first Olympic team gold in nearly 30 years.

The Americans hung on for silver and Great Britain won bronze.

Osaka, who was born in Japan and grew up in the United States, struggled with her usually reliable groundstrokes and lost 6-1, 6-4 in the third round to former French Open finalist Marketa Vondrousova of the Czech Republic

ALASKA GOLD

Seventeen-year-old Lydia Jacoby of Alaska pulled off a stunning victory in the women’s 100-meter breaststroke, upsetting American teammate and defending champion Lilly King.

Only a handful of Alaska swimmers had even qualified for the U.S. Olympic trials. Jacoby was the first to ever make the team.

STREAK SNAPPED

The streak of 12 straight gold medals for the U.S. men in the individual backstroke ended when a pair of Russians beat out defending Olympic champion Ryan Murphy in the 100-meter race.

STREAK EXTENDED

The U.S. women’s basketball team opened play with an 81-72 win over Nigeria that extended the Americans’ win streak at the Olympics to 50 games.

A’ja Wilson scored 19 points and grabbed 13 rebounds in her debut.

MOVING ON

The United States made it through to the quarterfinals of the women’s Olympic soccer competition after a 0-0 draw with Australia.

The Americans are looking to win a fifth Olympic gold medal in Tokyo. They are also vying to become the first team to win at the Olympics following a World Cup title.

HISTORIC FIRST

Flora Duffy has won the Olympic women’s triathlon, earning Bermuda’s first gold medal ever and first medal of any kind since 1976.
