PARIS — Serena Williams has lost in straight sets in the fourth round of the French Open.
Williams was beaten 6-3, 7-5 by Elena Rybakina on Sunday.
Williams is a 23-time Grand Slam champion who has won the title at Roland Garros three times. But the 39-year-old American hasn't been past the fourth round there since she was the runner-up in 2016.
This was the 64th time Williams has appeared in that round at a major tournament.
It was the first such match for Rybakina. She is a 21-year-old from Kazakhstan who is ranked 22nd.
Williams' exit came on the same day that Roger Federer withdrew from the tournament -- and a week after Naomi Osaka pulled out, citing a need for a mental health break.
