It's been an impressive run for the United States at Roland Garros on the men's side, but the American women will try to upstage them on Monday.
Coco Gauff got them off to a great start with a 6-0, 7-5 victory over No. 20 seed Ekaterina Alexandrova on Court Philippe Chatrier.
Gauff returned serve impeccably and made the most of her break point chances, converting five of nine. She was broken just once despite landing only 59 percent of her first serves in play.
The two each struck 14 winners, but Gauff was far cleaner with unforced errors, making just 16 to Alexandrova's 33.
"I thought I played well, she's a tough opponent," Gauff told Sloane Stephens after the match on TNT. "In the second set she started blasting some winners; felt like I wasn't playing that bad, but that's her game."
