Carlos Alcaraz saw his hopes of a hat-trick of titles at the Madrid Open ended in stunning fashion by Andrey Rublev on Wednesday.
Rublev earned the biggest win of his career on clay by defeating Alcaraz 4-6 6-3 6-2 under the roof of Manolo Santana Stadium.
The seventh seed struck 30 winners and frequently stepped inside the baseline to rush the Spaniard, who was below-par following his fourth-round battle against Jan-Lennard Struff.
Backed by a partisan home crowd, which included former Spain international footballers David Villa and Raul and Real Madrid star Luka Modric, the 20-year-old began well.
But underdog Rublev swung the momentum by breaking serve in the second game of the second set before dominating the remainder of the contest to set up a semi-final against American Taylor Fritz, who beat Argentinian Francisco Cerundolo 6-1 3-6 6-3.
Alcaraz, who missed clay-court events in Monte-Carlo and Barcelona due to a right arm injury, follows fellow Spaniard Rafael Nadal, a four-time winner of the competition, out of the tournament in a disappointing 24 hours for home fans.
