Simone Biles withdraws from women's gymnastics team final, U.S. wins silver
After a rare stumble on her first vault, American gymnastics star Simone Biles withdrew from the team competition, leaving Team USA's Suni Lee, Jordan Chiles and Grace McCallum to finish the event. Biles, considered the greatest gymnast in history, said after the competition that she wasn’t injured but wasn’t in the right headspace to continue.
“Today has been really stressful,” Biles said at a press conference. “After the performance that I did (on vault), I thought it was better if I took a step back and let these girls go out there and do the job, and they did just that.”

This rematch of the 2008 gold medal game — which was the last year softball was included in the Olympics — ended similarly with a 2-1 loss to Japan.
