Coco Gauff Struggles Serve Amid Emotional US Open Win

Coco Gauff has been facing significant challenges with her serve during the 2025 US Open, prompting a coaching change to biomechanics expert Gavin MacMillan just days before the tournament. Despite her shaky serve and emotional moments, including bursting into tears during a second-round match against Donna Vekić, Gauff managed to advance through tough three-set battles, showing resilience and mental strength. She credits trusting the new serve motion and maintaining focus during critical moments for her victories, though her serve remains inconsistent, with a notably high number of double faults this season. Simone Biles has been a vocal supporter, praising Gauff's maturity and ownership of her career decisions amid the mental demands of high-level competition. Gauff's family, particularly her mother Candi, has also expressed pride and encouragement publicly, highlighting the emotional and physical toll of her hard-fought wins. As Gauff continues in the tournament, her ability to overcome serve struggles while maintaining composure remains a key storyline.
