Roger Federer's bid for a ninth Wimbledon title lay in tatters after he was stunned in straight sets by Hubert Hurkacz in the quarter-finals.
The Swiss lost 6-3 7-6 (7-4) 6-0 to the 14th seeded Pole, who reached his first Grand Slam semi-final.
It is the first time 20-time major champion Federer has lost a set to love at the All England Club.
Hurkacz will play Matteo Berrettini or Felix Auger-Aliassime for a place in Sunday's final.
"It's super special for me," said Hurkacz, only the second Polish man to reach the semi-finals at a Grand Slam.
