that Coco Gauff\u2019s serve has improved \u201cbiomechanically\u201d despite the American star\u2019s continued struggles.<\/p>\n<p><a href=\"https:\/\/www.tennis365.com\/tag\/coco-gauff\">Gauff<\/a> hit the most double faults among all <a href=\"https:\/\/www.tennis365.com\/wta-tour\">WTA Tour<\/a> players in 2025 (431) and 2024 (430), and she also leads this unwanted statistic so far in 2026 with 103 double faults across her 14 matches.<\/p>\n<p>The American star hired Gavin MacMillan, a biomechanics expert and coach, ahead of the US Open in August last year with the intention of solving her persistent problems with her serve.<\/p>\n<p>The 21-year-old joined forces with MacMillan after parting ways with her previous coach Matt Daly, who had helped her win her second Grand Slam title at the 2025 French Open.<\/p>\n<p>Macci, a former coach of Serena and Venus Williams, credited MacMillan for his work with Gauff while suggesting that the world No 4 should switch to a platform serve stance.<\/p>\n<p>\u201cCoco and her serve is biomechanically better. Gavin identified the real problems and I see it is stabilised,\u201d Macci wrote on his X\/Twitter account.<\/p>\n<p>\u201cBut because she is double jointed and her wires are so free flowing she has more shake and bake that causes extra movements in the arm without trying.<\/p>\n<h2>More Tennis News<\/h2>\n<p><a href=\"https:\/\/www.tennis365.com\/tennis-news\/indian-wells-2026-aryna-sabalenka-elena-rybakina-prediction-martina-navratilova\"><strong>Sabalenka, Rybakina, Swiatek, Gauff?

But when you\u2019re out there double-faulting eight, 10, 12 times, or whatever, and you\u2019re still winning, how good could you be when you\u2019re only hitting a couple?<\/p>\n<p>\u201cI mean that\u2019s like crazy. I mean, your mind has to be made of granite. I mean, a lot of girls would disappear into outer space. So I just have so much respect for Coco.<\/p>\n<p>\u201cBut to be great, it\u2019s a package, and if this serve could be modified, I have no doubt where she could end up \u2013 double digits (Grand Slams) is around the corner for Coco.\u201d<\/p>\n<p><strong>READ NEXT: <a href=\"https:\/\/www.tennis365.com\/tennis-features\/indian-wells-open-seeds-aryna-sabalenka-no-1-coco-gauff-leads-americans-victoria-mboko-alex-eala\">Indian Wells Open seeds: Sabalenka No 1, Gauff leads six Americans, youngsters Mboko and Eala on list<\/a><br \/>\n<\/strong><\/p>\n<\/div>\n<\/section>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>Coco Gauff\u2019s serve is \u2018biomechanically better\u2019 as the real problem is revealed by legendary coach Ewan West 02 Mar 2026 6:00 PM Coco Gauff serving with Rick Macci inset Legendary coach Rick Macci has assessed that Coco Gauff\u2019s serve has improved \u201cbiomechanically\u201d despite the American star\u2019s continued struggles.
