US Open 2025: Coco Gauff turns to Aryna Sabalenka’s former biomechanics coach on the eve of the Grand Slam

Adjusting the skills to enter the tournament with such crazy attention and high bets feels like a risky move, but it can pay off for players who are usually able to recover from technical failures during the game.
However, 16 double faults were encountered in the Cincinna essay of Jasmine Paolini, the last straw, and immediately took action.
Gauff was on the driving range in Macmillan’s ongoing rains on Wednesday – showing how long she will fine-tune her own game before the singles starts Sunday.
Macmillan’s anatomical study of Sabalenka focused on improving her mobility, weight changes and angles, working strongly on forehand and serve.
This led to the Belarusian’s transition from a top ten player to a Grand Slam title, who has dominated the WTA Tour for most of the past two years.
In an interview with performance plus tennis last year,,,,,, External Macmillan talked about the difficulty of improving technology during a limited time to practice during the WTA tour.
The Canadian played hockey as a teenager before switching to a tennis scholarship, with little time before Goff started the U.S. Open.
So before Goff faces Australia’s Ajla Tomljanovic, rebuilding her confidence may be as important as technology – ranking 84th in the world in the first round of Flushing Meadows in a few days.
