Coco Gauff Survives First-Round Scare Against Ajla Tomljanovic at US Open

Coco Gauff survived a challenging first-round match at the 2025 U.S. Open, defeating Ajla Tomljanovic 6-4, 6-7(2), 7-5 despite struggling with her serve and committing 10 double faults. Gauff recently added biomechanics specialist Gavin MacMillan to her coaching team to address her persistent serving issues, which had resulted in a high number of double faults earlier in the season. Despite a shaky start, including being broken six times and multiple double faults, Gauff showed resilience by breaking back crucially and maintaining composure in the deciding set to secure the win. Tomljanovic, a veteran player known for her fighting spirit, pushed Gauff to the limit and forced a tiebreak in the second set, showcasing her competitiveness. Gauff's victory sets up a second-round match against Paris Olympics silver medallist Donna Vekic. This performance highlights Gauff's ongoing efforts to improve her serve mechanics while continuing to compete at a high level in major tournaments.
