Simone Biles arrived in Tokyo as the star of the U.S. Olympic movement and perhaps the Games themselves. She convinced herself she was prepared for the pressure. That she was ready to carry the burden of outsized expectations.

Only, as the women’s gymnastics team final approached on Tuesday night, something felt off. And the athlete widely considered the Greatest of All Time in her sport knew it.

So rather than push through the doubts that crept into her head as she’s done so many times in the past, Biles decided enough was enough. She was done. For now.

The American star withdrew from the competition following one rotation, opening the door for the team of Russian athletes to win gold for the first time in nearly three decades.

Jordan Chiles, Sunisa Lee and Grace McCallum guided the U.S. to silver while Biles cheered from the sideline in a white sweatsuit, at peace with a decision that revealed a shift not only in Biles but perhaps the sport she’s redefined.

“We also have to focus on ourselves, because at the end of the day we’re human, too,” Biles said. “So, we have to protect our mind and our body, rather than just go out there and do what the world wants us to do.”

The Americans — fueled by an uneven bars routine by Lee that not even Biles could match — drew within eight-tenths of a point through three rotations. ROC, however, never wavered on floor. And they erupted when 21-year-old Angelina Melnikova’s score assured them of the top spot on the podium for the first time since the Unified Team won in Barcelona in 1992.
