She hired the acclaimed serve fixer, Gavin MacMillan. He helped World No. 1 Aryna Sabalenka overcome her serving yips a few years ago.<\/p>\n

Since then, the serve has been inconsistent. Gauff\u2019s talent and athleticism have helped her overcome the double faults against lower-ranked players. <\/p>\n
On Friday, in a marathon match against Elina Svitolina, Gauff<\/a> lost the match and her cool, weeks after smashing her racquet following her Australian Open loss.<\/p>\n MORE: Australian tennis star reveals racist epithets that led her to retire at 25<\/a><\/p>\n What A Frustrated Coco Gauff Yelled To Her Coach<\/p>\n Fans noticed that Gauff was hitting her head with her racquet. That unusual move was accompanied by a one-sided conversation, presumably with MacMillan, where Gauff said she was doing what he told her to do for the last six months.<\/p>\n Coco Gauff after hitting a double fault against Elina Svitolina in Dubai<\/p>\n “I’ve been doing everything you’ve wanted for the last 6 months\u2026”<\/p>\n This is presumably to her biomechanics expert, Gavin MacMillan, who she hired before the US Open last season to help with her serve. pic.twitter.com\/eobBoCyHDP<\/a><\/p>\n \u2014 The Tennis Letter (@TheTennisLetter) February 20, 2026<\/a> <\/p>\n Coco Gauff after that double fault you can see how much it meant to her.

She is a fan favorite during March\u2019s US Sunshine Double at the WTA 1000 tournaments in Indian Wells and Miami. With serving concerns still on the horizon, will she make a coaching change before the Sunshine Double?<\/p>\n In addition to being hyper-focused on her serve, Gauff has played less doubles. She is a great doubles player and the 2024 French Open doubles champion (with Katerina Siniakova). Some believe she should play doubles to reduce her stress and work out the serving kinks.<\/p>\n MacMillan\u2019s help transformed Aryna Sabalenka\u2019s serve. She was in a similar situation with frequent double faults. Her serve has become one of the dominant features of her game and the reason she has stayed at World No. 1 for several years. <\/p>\n Australian Open champion Elena Rybakina also has a superior serve. Women\u2019s tennis is now ruled by tall players with big serves, and it is up to Gauff and the others to catch up.<\/p>\n \u2014\u00a0Enjoy free coverage of the top news & trending stories on The Big Lead\u00a0<\/a>\u2014<\/p>\n OLYMPICS:\u00a02026 Winter Olympics medal count, standings entering February 20<\/a><\/p>\n NFL:\u00a0Predicting the 2026 NFL free agent signings<\/a><\/p>\n MLB:\u00a0Detroit Tigers drop unreal alternate jerseys for 2026 MLB season<\/a><\/p>\n NBA:\u00a0Charlotte Hornets share update after LaMelo Ball\u2019s car crash<\/a><\/p>\n NHL:\u00a02026 Winter Olympics men\u2019s hockey, NHL payrolls for final four teams<\/a><\/p>\n SPORTS MEDIA:\u00a0Olympics reporter apologizes for drinking, slurring words during live segment<\/a><\/p>\n \t\t\t\t![\"\"](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2026\/02\/default-841-scaled-e1771618740262-1024x955.jpg\")
