Pegula has never lost to Potapova, leading 2-0 in tour-level head-to-head meetings.

“That was definitely a battle today,” Pegula said. “I just felt like I started off a little slow. She had some confidence, you know, going, obviously going for a lot of her shots. She just won a tournament as well.

“I’ve played her before, once where I won a little bit easier and once where I also had a really tough match with her. I wasn’t completely surprised. I know she can play really well, and she definitely came out hitting her shots and painting lines and going after it.

“So I’m just glad I was able to work my way back into the match, and, you know, ended up playing much better than how I started.”

The the all-18 battle between No. 6 seed Coco Gauff and Linda Noskova went to Gauff who took it 6-4, 6-3. In the match, Gauff hit seven aces, won 30/34 (88%) on first serves, faced 1 break chances. Gauff never lost serve, while breaking the Czech three times in the match. Gauff turns 19 on Monday.

“I think she played the match the right way,” Gauff said. ” Today I just played a little bit better in certain moments. I watched her play a lot of her matches this year in Adelaide and Australia. Yeah, she’s a great player. I think hopefully we will have many more battles in the future. I think she’s going to keep rising up the rankings and keep doing better and better each tournament.”
