Coco Gauff, the rising tennis star, is facing a challenging period with her serve, prompting questions about her decision to work with biomechanics coach Gavin MacMillan. Despite her trust in the process and belief in her serve's improvement, Gauff's recent performance has raised concerns. With 67 double faults in 11 matches in 2026, Gauff's serve issues persist, unlike the quick fix seen in Aryna Sabalenka's case. However, Gauff remains patient and committed to her strategy, stating, 'I'm trusting the process... I'm trying to figure out the recipe.' This approach, while encouraging, has not yet yielded the desired results, leaving fans and experts alike wondering if a change in strategy is necessary. As Gauff navigates this learning process, the tennis world watches with anticipation, eager to see if her partnership with MacMillan will bear fruit or if a new approach is needed to unlock her full potential.
