Karolina Muchova reached the first Grand Slam final of her career on Wednesday, coming through a tense, swinging Wimbledon semifinal against Coco Gauff that was decided by the narrowest of margins in a final-set tiebreak. The Czech won 6-2, 1-6, 7-6 (12-10), ending an absorbing contest and, with it, Gauff's breakthrough run on the grass.

How it was won

Muchova took charge early, racing through the first set as Gauff struggled with her timing, before the American roared back to level the match with a one-sided second set, ESPN reported. The decider went the distance and into a tiebreak that see-sawed for several minutes; Gauff held a match point, only for Muchova to save it and, after a run of tense exchanges, close it out 12-10, Forbes reported. "It was such a big fight," Muchova said afterward, calling it "very nerve-wracking."

A comeback rewarded

For Muchova, the win caps a return to form after a wrist injury disrupted much of her 2025 and, at one low point, left her hitting only a one-handed slice off that side. A stylish, all-court player admired by fans and peers, she has long been rated as a potential major champion but had fallen short in the biggest matches. Reaching a first final, at Wimbledon, is the reward for a patient comeback. "It sounds really nice to be in the final," she said.

Heartbreak for Gauff

For Gauff, the defeat is a painful end to what had been a genuine breakthrough on her least favorite surface. The 22-year-old, already a two-time major champion on hard court and clay, had never gone deep at Wimbledon before this fortnight, and she spoke during the tournament of finally putting in a proper block of grass-court preparation. That work carried her to the last four, and to the brink of a final, before Muchova edged her out. Losing from a match point up will sting, but the run marks real progress on grass.

The final to come

Muchova will play the winner of the other semifinal, between Marta Kostyuk and Linda Noskova, which was still to be resolved as her match finished. Whoever emerges, the women's final is guaranteed a first-time Wimbledon champion, part of an unusually open tournament on the women's side. On the men's side, by contrast, familiar names in Novak Djokovic and Jannik Sinner reached the semifinals. For Muchova, one match now stands between her and a maiden Grand Slam title, and, whatever the result, a fortnight that has already reshaped her season.
