Sloane Stephens dominates No. 16 seed Karolina Pliskova, as U.S. women start Day Two 4-0

PARIS (AP) — Back on her "favorite court in the world," Sloane Stephens looked sharp in her opening match at the

French Open with a 6-0, 6-4 win over two-time major finalist Karolina Pliskova.

While Stephens' only Grand Slam title came at the 2017 U.S. Open, she's also had sustained success at Roland Garros, finishing as a runner-up to Simona Halep in 2018 and reaching two quarterfinals on the red clay in Paris — including last year.

"This is my favorite court in the world, so I'm super happy to be back," Stephens told the crowd on Court Philippe Chatrier. "To start a Slam on your favorite court, your favorite surface, is always incredible."

She helped American women go 4-0 through the first few hours of play on Day 2 of the tournament after a 1-4 start on Sunday, when the only U.S. victory came in a match between two players from the country: Jessica Pegula beat Danielle Collins.

Madison Keys, the runner-up to Stephens in New York six years ago and a semifinalist at Roland Garros in 2018, beat Kaia Kanepi 6-1, 3-6, 6-1 on Monday to improve her career record in the first round of majors to 35-5.

Keys next plays American qualifier Kayla Day, who eliminated French wild-card entry Kristina Mladenovic 7-5, 6-1.

Also, Croatian-born American Bernarda Pera beat former No. 2-ranked Anett Kontaveit 7-6 (6), 6-2.

Anastasia Pavlyuchenkova, a finalist in Paris in 2021, breezed past Czech teenager Linda Fruhvirtova 6-2, 6-2; and 22nd-seeded Donna Vekic beat qualifier Dayana Yastremska 6-2, 7-5.

Stephens was down a break in the second set against Pliskova but then won three straight games to close it out.

Stephens had a 19-16 edge in winners and committed only 10 unforced errors to 31 by Pliskova, who lost in the finals of the U.S. Open in 2016 and Wimbledon in 2021.

"This court is a bit tricky. You have to play on it a lot to understand when the wind is blowing and where it's coming," Stephens said. "The more you play on it, the more you understand it. But it's a very complicated court. But that's what makes it so amazing."

Stephens won a small clay-court tournament in Saint Malo, France, at the start of the month and also reached the semifinals of the Morocco Open last week after only playing a total of three matches at bigger clay events in Madrid and Rome.

"Last year, my clay season wasn't great, but I played amazing at Roland Garros last year," Stephens said, "and this year, I really wanted to get matches and play a lot and to see where that got me."
