Coco Gauff's serve has vital flaw says former Serena Williams coach Rick Macci after double fault laden US Open defeat
WTA
Coco Gauff's US Open campaign came to a shuddering halt on Sunday night at the hands of Emma Navarro who sealed a 6-3, 4-6, 6-3 win and beat the defending champion again.
But Rick Macci who previously coached Serena Williams pointed a vital flaw that was evident in the Gauff game as she was defeated. That being her serve. It deserted her at key moments and Navarro in reality should've won even easier.
It was 19 double faults for Gauff as her serve once again was bludgeoned. A usual issue for Gauff in her game that can sometimes affect her more times than others, it was evident mostly in this tie.

Navarro sealed back-to-back Grand Slam wins over her compatriot. The 23-year-old has been ever improving and is now in the top 10 after adding to her Wimbledon win over Gauff who now plummets out of the top five. Now Paula Badosa awaits for a spot in the semi-finals. While for Gauff, it is firmly back to the drawing board.
"Asked about Coco and her serve. Biomechanically it is disconnected. 19 double faults and be in there shows her greatness. It needs minor reconstruction surgery based on scientific principles as it is an easy fix. People are telling her the Symptom not the Culprit. @Cocogauff"
But while he picked apart Gauff, he was full of praise for Navarro. He said he was impressed by the improvements that she has been making to her game as well as her strong mindset.
"What I love about Emma Navarro besides her improvising skills is her mindset. What we on the outside with the dips flips rips slices and dices does not show up on the biggest Stage unless SHE HAS THAT INTENSITY AND CALMNESS ON THE SAME PAGE," he also wrote.

- Vukov is doing this to Lena... AGAIN!!!!! WTA's autonomous collective should be dismantled for allowing Vukov to re-emerge from his hand-slapping suspension. Just ask WTA employees how that's been going lately as they witness his continued verbal abuses. Women's Pro Tennis should start over.
mandoist08-11-2026 - Can't help but suspect Vukov is back to his old self again. Thank you, WTA. Perhaps you can give them a "Battling Couple of the Year Award 2026" ??
mandoist08-11-2026 - Wtf? Why is there no reason? And what about the men's?Bel08-11-2026
- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.
mandoist06-11-2026 - Enough of her bullshit. Go marry someone.
mandoist06-11-2026 - Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.
mandoist05-11-2026 - Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.
mandoist05-11-2026 - Vacherot is Mongasque, rather than Swiss. The tournament was Swiss :DTrwd7702-11-2026
