Gilbert and Stubbs weigh in on Gauff's serving struggles at US Open: “Under pressure, bad technique breaks down.”
WTA
Coco
Gauff’s coach, Brad Gilbert, listened to the criticisms from Rennae Stubbs
following his player’s elimination from the US Open. The 2023 champion was
ousted in the fourth round after an inconsistent match against the 13th seed
Emma Navarro, in a duel marked by Gauff’s 19 double faults.

During the
television broadcasts, the experienced coach participates as a commentator
during the Grand Slams and was part of the expert analysis following the world
No. 3’s defeat. Gilbert was asked about the loss of confidence that Gauff
exhibited throughout the match: “It’s funny, we go to the practice courts and
it’s fine,” he started.
“Hasn’t
been a problem but all of a sudden - you know, listen, for me the most
important thing that gotta get right is being able, when you are in a
situation, is being able to hit one speed. It’s like, okay, just hit 85 [mph]
in the middle of the box, a working serve and then move on.
“Because
with the women, it’s a little different than men’s second serves, and a lot of
women are more aggressive on the second serve returns but I still feel like
it’s just that one constant speed, being able to hit in the middle of the box
like 85, 90. Serena had a massive first serve but she didn’t have a massive
second. But she had a great, working serve that she could rely on.”

Regarding
this, Rennae Stubbs, former coach of Serena Williams, spoke about how
detrimental Gauff’s serve was in the match: “That’s the thing. I mean, the
thing with Emma [Navarro] is that she’s always looking to attack, and most
women are looking to attack because they often see a slow second serve in
women’s tennis not like in the men’s.”
“But the
difference with Coco’s, as you said, sometimes she was hitting in the mid-90s
the second serve. Then she was going a little bit slower in the middle. There’s
no second serve that’s the same, and that’s a problem. So under pressure, bad
technique breaks down.”

The former
world No. 1 in doubles acknowledged that it was difficult to criticize Gauff
with Brad Gilbert sitting next to her, but continued with her analysis: “And
her technique - and it’s hard for me to say it because Brad’s sitting here as
her coach and all. But the technique, the elbow is too low, the grip I feel
like is a little weird as well,” Stubbs continued.
“So it’s
hard to get nice massaging first serve or, we call it a three-quarter pace
first serve, and then same or similar as a second serve. But you’ve got to be
able to hit your spots on a second serve under pressure. And as you say, she
served great in practice."

“And I hate
to say this, but more people serve great in practice because they don’t have
15,000 people eyeing them and millions of people watching on TV. And Billie
Jean King always says bad technique breaks down under pressure and
unfortunately for Coco, this year, that’s what happened. Because she’s not
confident as well,” she added.
“I
definitely want to get other opinions because, you know -- and also I think
it's sometimes more of an emotional, mental thing because if I go out on the
practice court right now, I would make, like, 30 serves in a row. I've done it
before,” she said.
“I think
it's also just kind of a mental hurdle that I have to get over when it comes
with that. But, yeah, I definitely want to look at other things because I don't
want to lose matches like this anymore.”

- 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
- After a couple decades traveling to IIHF tourneys overseas... our family is done with it... and I will not be the only one!! Bad enough the NHL allows Ovachenko (a Putin Supporter and Campaigner) to live and play in the USA. Let's not forget the STATE SPONSORED RUSSIAN DOPING PROGRAMS still in effect today.
mandoist31-10-2026 - Osaka's mental state apparently does not allow her to reach any more Quarter Finals? I mean, she doesn't really have the time for tennis with all the pre-planning that must go into her 12 year-old "fashion" goals.
