Overview

• Coco Gauff split with coach Matt Daly ahead of the US Open and hired biomechanics specialist Gavin MacMillan to address persistent double faults.
• Elena Dementieva said on the Hardcourt podcast that Gauff would benefit more from reworking her forehand and suggested the double faults may not be purely technical.
• Gauff’s 2025 double‑fault tally is reported to exceed 350, with cited totals including 38 at Indian Wells, 42 at the Italian Open, 27 across four US Open matches, and 31 in five China Open matches.
• In the China Open semifinal, Amanda Anisimova beat Gauff 6‑1, 6‑2 as Gauff served five double faults and won 38% or less of her second‑serve points according to the reported figures.
• Reports note MacMillan’s prior work with Aryna Sabalenka, and Gauff has said her focus for the rest of 2025 is improvement rather than immediate results as she turns next to the Wuhan Open.
