First-seeded Cori "Coco" Gauff won her second-round match in straight sets, 6-2, 6-2, over Romanian Selma Stefania Cadar, before the youth matches were suspended due to the heat.

The 14-year-old enters this tournament as the second best player in the world after winning the girls' title at the French Open earlier this year. She received a wild card at the US Open last year and became the youngest player to reach the women's final.

Gauff's father, Corey, played basketball at Georgia State and his mother, Candi, ran at Florida State.
