Prior to this season, the American carried an 11-12 record on clay. After her 6-1, 5-7, 6-4 victory over Anhelina Kalinina on Thursday, Pegula's record on clay is 9-3 on the season and she is into the third round at Roland-Garros for the first time.
The 28-year-old will next face Slovenia's Tamara Zidansek, the architect of a feel-good run to the semi-finals last year. It is an opportunity that the suddenly solid on clay Pegula relishes.
"I have a really good chance to kind of break through the draw," Pegula said on Thursday, of her wide open section of the draw. "I hope I can do that. But feeling good and I'm moving well and feeling I think more confident than I did last year."
Pegula defeated Zidansek in their only previous meeting, 6-3, 6-3 at Auckland in 2020, but knows that the 24-year-old world No.25 is a far tougher out on the red clay.
At the very least, she's hoping it will be easier than her two hour and 26-minute battle with Kalinina on Court 7. Pegula served for the win at 6-2, 5-2 but couldn't capitalise on a bevy of match points, including five in the final game before she tapped a volley winner to close the gruelling contest.
