Overview

• Coco Gauff defeated Donna Vekić 7-6 (5), 6-2 on Arthur Ashe Stadium to advance to the US Open third round.
• Gauff double-faulted seven times and was broken four times in a chaotic first set, then steadied to take the tiebreak.
• She regrouped after a locker-room break and committed just one double fault in a cleaner second set, holding all service games.
• Gauff has led the tour with 300-plus double faults this season and recently hired biomechanics specialist Gavin MacMillan to remodel her serve.
• The American grew emotional during play and in her on-court interview, later noting inspiration from Simone Biles in the crowd, and will face No. 28 seed Magdalena Fręch next.
