Grigor Dimitrov stuns top-seeded Carlos Alcaraz in straight sets to reach Miami Open semis

Eleventh-seeded Grigor Dimitrov came out strong against top-seeded Carlos Alcaraz on Thursday night and went on to win 6-2, 6-4 in the Miami Open quarterfinals, his first victory over a top-five player in nearly five years.

Fourth-seeded Alexander Zverev, who beat unseeded Fabian Marozsan 6-3, 7-5, will play Dimitrov in the semifinals Friday. Second-seeded Jannik Sinner will face No. 3 Daniil Medvedev in the other semifinal, a rematch of last year's final that Medvedev won.

Alcaraz, the 2022 champion, entered this tournament off a victory over Medvedev at Indian Wells. But the world's second-ranked player had trouble finding his game against Dimitrov and became visibly frustrated numerous times in the first set.

Alcaraz, however, didn't go away even after falling behind a break at 4-2 in the second set. He broke Dimitrov at love and then held serve to even the set at 4-4. But then Dimitrov won the final two games, breaking Alcaraz in the clincher.

This was Dimitrov's first victory over a top-five player since he beat then-No. 3 Roger Federer in the quarterfinals of the 2019 U.S. Open.

On the women's side, fourth-seeded Elena Rybakina once again had to go three sets, pushed to the edge before beating No. 27 Victoria Azarenka 6-4, 0-6, 7-6 (2) in the semifinals.

Rybakina, ranked fourth on the WTA Tour, will face No. 14 Ekaterina Alexandrova or unseeded Danielle Collins in the final Saturday. Rybakina also made last year's final, losing in straight sets to Petra Kvitova.

"This year, it's much different," Rybakina said. "I was not expecting, honestly, to be in the final because I was not prepared that well for this tournament, but really happy that I managed to battle through all these matches and be in the final again."
