American tennis star Sofia Kenin won't compete at Tokyo Olympics

The highest-ranked American singles tennis player on the planet won't be participating in the Summer Olympics in Tokyo. 

Following her second-round Wimbledon loss to fellow American Madison Brengle, Sofia Kenin confirmed on Wednesday she's opting out of playing in the Olympic tournament. 

"Yeah, I'm not playing the Olympics," Kenin said during a news conference, according to Kathleen McNamee of ESPN. "Yeah, that was a difficult decision, but I spoke and discussed that with my agents.

"I couldn't take anyone with me, and I definitely wanted to have someone. Of course I love the Olympics. It was a tough one, like I said." 

McNamee added that Kenin, No. 6 in the current WTA rankings, originally said in February she wanted to play in Tokyo. 

All-time greats Serena Williams and Rafael Nadal are among the other big tennis names skipping the Olympics that were postponed last year due to the COVID-19 pandemic. Williams retired from Wimbledon on Tuesday after she suffered an injury early into her first-round match against Aliaksandra Sasnovich, and the 39-year-old's status for the rest of the summer and this year's U.S. Open is unknown.
