Coco Gauff's RISKY Coaching Change That Paid OFF! [2025 Decision Proven Right] (2026)

In the world of tennis, decisions made by players and their teams can often be met with skepticism, especially when they involve drastic changes on the eve of major tournaments. Such was the case with Coco Gauff's bold move in 2025, a decision that has since been validated by her improved performance on the court.

Last year, Gauff's game was plagued by an alarming number of double faults, a problem that threatened to undermine her talent and hard work. In a bold move, she decided to overhaul her coaching staff, bringing in biomechanics expert Gavin MacMillan, known for his success with Aryna Sabalenka.

This decision was met with criticism, with many questioning the timing and its potential impact on Gauff's performance at the US Open. However, as we reflect on the past year, it's evident that Gauff's choice has paid dividends.

MacMillan's expertise has clearly made a difference in Gauff's game. While she hasn't yet won a title in 2026, her serve has shown marked improvement. Her first serve percentage has increased, and she's winning a higher percentage of points on her first serve. Even her second serve has seen an improvement, with a decrease in double faults.

The statistics speak for themselves. In 2025, Gauff averaged 6.7 double faults per match, with some matches seeing her hit as many as 23. This year, her average has dropped to just 6.0, with a maximum of 16 double faults in a single match. This reduction is a testament to the work done by MacMillan and Gauff's dedication to her craft.

As Gauff heads into the US Open, there's a renewed sense of optimism surrounding her chances. Her improved serve, a key aspect of her game, gives her a solid foundation to build upon. While the road to a Grand Slam title is never easy, Gauff's decision to trust her instincts and make a bold change has set her on a path of progress and potential.

In my opinion, Gauff's story serves as a reminder that sometimes, taking risks and trusting your instincts can lead to remarkable outcomes. It's a testament to the power of self-belief and the impact a fresh perspective can have. While the tennis world may have initially questioned her decision, Gauff's journey highlights the importance of staying true to your vision and embracing change when necessary.
