Coco Gauff’s performance at the National Bank Open in Montréal reignited concerns about her serve, as she recorded 33 double faults across the tournament. This placed her third for most double faults in a single WTA-1000 event this season, trailing only her own tallies in Rome (42) and Indian Wells (38).
A Persistent Pattern
Despite her rise in the rankings and Grand Slam success, Gauff’s serve has remained a vulnerable part of her game. In Montréal, she struggled in her second-round match against Danielle Collins, committing 23 double faults. The match lasted nearly three hours, and Gauff narrowly escaped with a 7-5, 4-6, 7-6 (2) win.
Mental Fortitude Amid Technical Flaws
Gauff continues to win matches despite serving troubles. Her resilience and mental strength help her overcome deficits and high-pressure moments, as shown in Montréal when she battled back from the brink of defeat.
Calls for Technical Adjustments
Experts and coaches have suggested biomechanical tweaks to improve her serve. Rick Macci noted that the issue could be resolved with targeted adjustments. Whether Gauff makes those changes remains uncertain, but the statistics indicate growing urgency.
Looking Ahead
As the hard-court season progresses, Gauff will need to address her serving inconsistencies to maintain her momentum. With the US Open approaching, her ability to minimize this flaw could shape her performance on tennis’s biggest stage.
