“How old is she? 18, 19? It's just ridiculous,” quipped Pegula. "I feel like she's been 18 for like five years. I'm like, ‘Coco, you're like a veteran’.
“She has so much time, so I hope she doesn't get too stressed out about that either, because I'm sure she will have many more chances. But, yes, we're definitely hoping she gets to that final and then hopefully in doubles too.”
Pegula and Gauff have lined up a stars and stripes semi-final, taking on Madison Keys and returning mom Taylor Townsend.
“How exciting. At Roland-Garros, Four Americans. Wow!” beamed Pegula.
“Super happy for Taylor Townsend. She had a baby, just came back, literally a few tournaments ago. Just awesome for her. She's a sweet girl. She came to my wedding. I have nothing but good things to say.
“I played Madi a few times this year actually in doubles as well. Taylor's an amazing doubles player, Madi has a big game, so that will be interesting.
“Coco is a little younger, but we grew up playing with each other, so it will be really fun, I'm excited.”
