Overview
- Gauff exited the US Open in the round of 16, losing to Naomi Osaka 6-3, 6-2 in 64 minutes.
- She totaled 33 unforced errors, including 20 on the forehand, as Osaka won 94% of first‑serve points and dropped only six points on serve overall.
- Gauff replaced coach Matt Daly with biomechanics specialist Gavin MacMillan shortly before New York and adopted a new service motion after a brief, physically demanding lead‑up.
- She said she felt discombobulated on court and broke down after the match, then confirmed a training block before the China Open in Beijing later in September.
- Justine Henin criticized her forehand and lack of progress, while fans and Rennae Stubbs floated a longer hiatus that Macci publicly opposed.
