No-call on double bounce vaults Swiatek into French Open semis with 33rd straight win

Iga Swiatek benefited from the chair umpire's no-call on a double bounce that gave her a key first-set service break during a match-altering five-game run and the French Open's No. 1 seed moved into the semifinals with a 6-3, 6-2 victory over Jessica Pegula on Wednesday.

Swiatek extended her winning streak to 33 matches, the longest on tour since Serena Williams won 34 in a row in 2013.

Swiatek will face No. 20 Daria Kasatkina in one women's semifinal Thursday, when the other will be No. 18 Coco Gauff, an 18-year-old American, against unseeded Martina Trevisan, a 28-year-old from Italy.

Only Swiatek, who won the 2020 French Open, has previously participated in the final four at a major tournament.

Kasatkina made it that far by beating No. 29 Veronika Kudermetova 6-4, 7-6 (5) in a match between two Russian players who will not be allowed to compete at Wimbledon later this month because of that country's invasion of Ukraine.

Theirs was a mistake-filled quarter-final, with the players combining for 75 unforced errors, 50 by Kudermetova. That allowed Kasatkina to win despite coming up with just 16 winners over the course of 165 points.

A day after her 21st birthday, Swiatek was not at her dominant best against the 11th-seeded Pegula, a 28-year-old from New York whose parents own the NFL's Buffalo Bills and NHL's Buffalo Sabres.

"Getting old, but still fresh," Swiatek wrote with a silver marker on the lens of a courtside TV camera.

As usual for most of this season, Swiatek was good enough to end up on the right side of the scoreline. She has not lost a match since February and claimed the title at each of her past five tournaments.
