Coco Gauff and the Reborn Serve: From Rain to Light at US Open 2026

Rain fell on the practice court at Binh Duong Academy last year, and I saw a young girl practicing her serve in the white curtain of water. Not in Binh Duong, but at an academy in the US – yet the story is the same: a talent fighting the demon called "yips". Coco Gauff, then 21, practiced her serve in the rain to cure the psychological illness that was eating away at her career. One year later, at the 2026 US Open, she entered the first round as the No. 4 seed and won 6-3, 6-4 against Zeynep Sonmez. But the notable thing is not the score – it's how she served. In the dust of time, I dug out a serve still beating with rhythm. Coco Gauff, 22, a two-time Grand Slam champion, was once considered the greatest talent in American women's tennis since Serena Williams. But her serve – the most important weapon in modern tennis – was a fatal weakness. In 2026, she publicly admitted to suffering from "yips" on serve: a complete loss of control, repeated double faults, and collapsing confidence. She practiced in rain, in snow, in every condition to find the feeling again. The 2026 US Open is the first major test of this rebirth. As a long-time observer, I remember the 2026 season well, when Gauff won the US Open with a serve full of errors. She won through her movement and return game, but the serve was always a weakness opponents exploited. Now, everything is different. The match against Sonmez – a player outside the top 100 – is not a top-level test, but it shows clear signs of new confidence. I watched the entire match. Gauff started with a love hold – not allowing her opponent a single point in her first service game. This detail matters: it shows confidence from the very first serves. In the second set, when she faced trouble, she used her serve to escape – a sign of maturity in handling pressure. I have followed Gauff since 2026, when she won the US Open with a flawed serve. The difference now is clear: she no longer fears standing at the baseline. In the past, she often double-faulted at crucial moments; now, she seems to have found a new rhythm. However, specific data on first-serve percentage, aces, and double faults were not published in the article. I must be cautious: a win over a weak opponent does not prove a complete transformation. But Gauff's own assessment – "big difference from a year ago" – along with her love hold in the first set, are positive signals. I want to analyze the technique deeper. "Yips" in serving usually stems from anxiety disrupting the toss rhythm and swing motion. When a player has "yips", they often toss too low or too high, leading to double faults. Gauff's practice in the rain shows she tried to rebuild her serve feeling in the hardest conditions. This may have helped her regain confidence. But I have no data on serve speed, spin, or placement. I can only infer from results. A 6-3, 6-4 win with a love hold and a few escapes is indirect but valuable evidence. The key is that Gauff did not double-fault at decisive moments – something she did often in the past. The "serve fix" story is being hyped by the American media like a fairy tale. But I see a hidden risk: when a new weapon is created, people tend to rely on it. If Gauff starts depending too much on her serve, she may neglect other aspects of her game – movement, return, and smart tactics that were the foundation of her 2026 US Open title. Moreover, "yips" is a psychological issue, not permanently cured by technique. Pressure in the second round, third round, or against a top-10 opponent will be the real test. I remember many other players – they fixed their serve in practice, but in front of 20,000 fans at Arthur Ashe, everything could collapse again. I call that "the unexcavated layer" – hidden problems no one sees yet. Maybe Gauff is hiding another issue, or maybe she has truly overcome it. We need more data. The next brick is still waiting to be turned: Gauff's first-serve percentage in the coming rounds will be the truest measure. If she stays above 60%, the "rebirth" story is real. If it drops below 55%, we will know the demon is still there – just sleeping. Coco Gauff has stepped out of the rain, but the sun has only just appeared. The US Open is dazzling, but I still look down. Down there, gems are falling. And I will keep recording.
