Coco Gauff Overcomes Serving Struggles to Win US Open Second Round

American tennis star Coco Gauff faced significant struggles with her serve during her second-round match against Donna Vekic at the 2025 US Open, resulting in emotional moments on court, including tears. Despite these challenges, Gauff managed to win the match 7-6, 6-2, showcasing resilience and improved consistency in the latter stages, particularly during the tiebreak. Earlier this year, Gauff hired biomechanics expert Gavin MacMillan to help rebuild her serve, a move inspired by his work with top players like Aryna Sabalenka, but she continues to grapple with double faults, leading the tour with over 300 this season. Gauff credited the support of the crowd and her motivation to push through tough periods, emphasizing her emotional connection to the sport and her fans. Although her serve velocity has dropped as she adjusts to a new serving motion, her baseline defense and mental toughness have helped her advance in the tournament. The victory sets up a third-round match against Magdalena Frech, with Gauff aiming to capture another US Open title after wins in 2023 and the French Open earlier this year.
