Overview

  • Gauff committed 16 double faults and 62 unforced errors in her 2-6, 6-4, 6-3 loss to Jasmine Paolini at the Cincinnati Open quarterfinals, extending her hard-court woes.
  • She has amassed 320 double faults through 14 events this season and averaged 9.2 per match over her last five outings while winning just 48.5% of second-serve points.
  • Former professionals Lindsay Davenport, Chanda Rubin and Rennae Stubbs all highlighted technical flaws and visible frustration undermining her serve under pressure.
  • Legendary coach Rick Macci and biomechanics expert Dr. Gordon have offered a science-based plan to overhaul her service motion and reduce errors.
  • Her switch to a two-coach setup with Matt Daly alongside Jean-Christophe Faurel after parting with Brad Gilbert has yet to resolve her chronic serve issues ahead of the US Open.
