Karolina Muchova saved a match point before coming through an epic deciding-set tie-break to beat Coco Gauff and reach a first Wimbledon final.
Muchova started the semi-final the stronger of the pair but Gauff hit back, and they could barely be separated in a high-quality third set.
Two-time Grand Slam champion Gauff came back from 4-1 down in the resulting tie-break and had match point on her serve, before sending a simple forehand into the net tape.
Muchova also missed her first match point but it was she who stood triumphant at the end after an astonishing 6-2 1-6 7-6 (12-10) win in sweltering conditions on Centre Court.
The Czech 10th seed had reached four major semi-finals before Thursday’s match against Gauff, but only once made the final – at the 2023 French Open, where she was beaten in three sets by Iga Swiatek.
But Muchova will get another shot at Grand Slam glory on Saturday, where she will face either compatriot Linda Noskova or Ukraine’s 12th seed Marta Kostyuk.
After clinching victory, Muchova buried her face in her towel as she took a moment to absorb the enormity of her achievement.
“It was very nerve-wracking. I don’t even know what I’m saying, I’m shaking and trying to sink it in,” the 29-year-old said.
“Honestly, it was such a big fight. It was a rollercoaster – match point and then match point down. You don’t have time to think.”
Muchova is the third Czech player in three years to reach the women’s singles final at the All England Club and will be hoping to emulate Marketa Vondrousova and Barbora Krejcikova’s successes in 2023 and 2024 respectively.
A series of unforced errors and a double fault saw Gauff drop serve early on in a one-sided first set, and she shanked a forehand wide when handed the chance to break back.
More misses on her forehand gifted Muchova a double-break lead and the Czech kept her level consistently high to serve out the first set with an ace.
Having taken a bathroom break before the second set, a re-energised Gauff returned with more aggression, and she eventually found a way past Muchova on her ninth break point with a sublime cross-court backhand winner.
The momentum stuck and Gauff flew through the next four games to force a deciding set to the delight of the crowd – the majority of whom appeared to be backing the seventh seed.
The tension rose as the third set unfolded and the pair entertained the 15,0000-strong crowd on Centre Court with top-quality groundstrokes and sensational quickfire play at the net.
It was fitting, then, that the match was decided with a tie-break, and from 4-1 down, Gauff somehow found a way to move level at 6-6.
The twists and turns continued as Muchova received a warning for a time violation at 8-8 on serve – and she immediately fired long to hand Gauff the first match point.
But the crowd were left gasping in anguish as Gauff, approaching the net, swiped the ball into the tape.
To add to the drama, Muchova slipped when she had the chance to convert her first match point, and Gauff produced an audacious lob to cling on.
But the young American could not salvage the next one, planting a low forehand into the net after an extraordinary two hours and 35 minutes.
