It’s not often a World No. 3 openly admits there’s a flaw in her game but Coco Gauff has never been one to hide from the truth.
The 21-year-old American sensation has set the tennis world ablaze with her explosive athleticism and fiery competitive edge. Yet even as she racks up major titles, Gauff knows one thing still holds her back her serve.
And the numbers tell the story. In the 2025 season alone, Gauff has racked up an eye-popping 405 double faults — more than any other player on the WTA Tour by a huge margin. Combine that with an occasionally unpredictable forehand, and it’s clear that Gauff’s biggest battles are happening within her own mechanics.
But now, she’s determined to fix it using what she calls a “logic-based” plan.
Inspired by Sabalenka’s transformation
To rebuild her serve from the ground up, Gauff has turned to biomechanics specialist Gavin MacMillan, the same expert who helped transform Aryna Sabalenka from a double-fault machine into a Grand Slam-winning powerhouse. Back in 2022, Sabalenka’s serve was crumbling under pressure until MacMillan redesigned it. The result? A world No. 1 ranking and a much more confident delivery.
Gauff is also studying Novak Djokovic’s early struggles to find inspiration. Speaking to The National, she explained:
“I was looking at Novak he didn’t have as great of a serve in the beginning, but he made that change and became Novak Djokovic. And obviously Aryna and Venus [Williams] have done those changes too.”
No mental block just logic
Some critics have hinted that Gauff’s serving woes are psychological, but the young champion disagrees.
“A lot of people thought it was mental,” she said. “But I knew for me, it wasn’t. I’m one of the mentally stronger players on tour. I just needed something that made sense something logical.”
It’s a grounded, analytical approach classic Gauff and it’s hard not to admire the maturity behind her words.
Still winning despite the flaws
What’s truly remarkable is that even with those serving hiccups, Gauff’s success hasn’t slowed down. She captured her second Grand Slam at Roland Garros earlier this year and followed it with a historic Wuhan Open title, proving she can win ugly and still dominate.
Now, as she heads to Riyadh to defend her WTA Finals crown, Gauff is chasing history a chance to become the first player since Serena Williams (2012–14) to win back-to-back year-end championships.
Her serve may be a work in progress, but if this “logic-based” rebuild works, Coco Gauff might not just fix her flaw —she could redefine what consistency looks like in modern tennis.
