Coco Gauff Advances Fourth US Open Round Maintaining Serve Improvements

Coco Gauff advanced to the fourth round of the 2025 US Open after a dominant 6-3, 6-1 victory over Magdalena Frech, marking her fourth consecutive year reaching this stage. Despite her ongoing struggles with double faults, Gauff showed significant improvement in her serve following the recent hiring of biomechanical coach Gavin MacMillan, who previously helped Aryna Sabalenka correct her serve. Gauff adopted a more patient strategy against Frech, focusing on controlled serves, quickness, and solid defense, which led to her winning 18 of 25 extended rallies and dominating the match in just 73 minutes. She acknowledged the emotional challenges of the tournament but expressed satisfaction with her performance and enjoyment on court, crediting her fans for their support. Gauff will next face either Daria Kasatkina or Naomi Osaka in the fourth round. Her progress reflects a turning point in her serving consistency and overall game management during the tournament.
