DOHA, Qatar -- Top-seeded lost for just the second time this year on Thursday when 25th-ranked beat him 6-3, 3-6, 6-4 in the quarterfinals of the Qatar Open. Alcaraz's only other defeat in 2025 was to in the Australian Open quarterfinals. The 21-year-old Spaniard, ranked No.
3, won the Rotterdam Open earlier this month. "I've talked with my team, with my coach, and honestly I don't know what I could have done better," Alcaraz said in a press conference. "Honestly, I don't know.
It was kind of a difficult feelings, I guess. I have to give credit to him as well, because when he was down, especially in the third set, he didn't give up." Alcaraz led 4-2 in the third set and had a break point on Lehecka's serve, but couldn't finish off the Czech, who won the next three games to advance to the semifinals.
The 23-year-old Lehecka will next play eighth-seeded , who knocked out 4-6, 6-4, 6-3. "The match was up and down since the beginning," Lehecka said after beating Alcaraz. "So for me to win a match like that against a player like this is a super big achievement.
I believed in myself. I knew that I had the level to produce that kind of tennis. "I didn't back down," he continued.
"I wanted to push him to his limits. The way I trusted my game was the key today." Earlier, fifth-seeded saved one match point and needed eight of his own to subdue second-seeded 6-1, 3-6, 7-6 (8).
Rublev reached his fourth semifinals in Doha, where he won the title in 2020. He'll next face Canada's , who beat when the Russian retired after losing the first set 6-3. "Unfortunately, I had food poisoning.
Very disappointed to end my run here in Doha like this as I feel like I was playing well," Medvedev said in a statement. Auger-Aliassime said on court he thought Medvedev was "playing normal" until he retired. "And then I broke, I held my serve.
And he just told (the umpire) that he didn't want to shake our hands because he was sick. I hope it's nothing too bad. I was surprised," the Canadian said.
