A Swift Revenge in the Spanish Capital

Alexander Zverev dismantled Flavio Cobolli 6-1, 6-4 on Thursday evening to reach the semifinals of the Mutua Madrid Open, exacting swift revenge for his loss to the Italian in Munich just twelve days earlier. The second seed needed less than 30 minutes to claim the opening set, racing to a 5-0 lead as Cobolli managed only 12 points in the first set. Zverev's serve was the decisive weapon: he fired down eight aces in the first set and finished the match with 12 aces, winning 82% of his first-serve points. Cobolli, the world No. 13 and 10th seed, never found a foothold, converting just 49% of points on his first delivery.

Cobolli's Fightback Falls Short

Cobolli, who had beaten Zverev 6-3, 6-3 in Munich and arrived in Madrid after eliminating Medvedev in the quarterfinals, showed signs of life in the second set. He did not earn a single break point until the final game of the match, when he had two opportunities at 5-4 down. Zverev closed it with four consecutive points to seal the victory. “Things can change quickly in sport,” Zverev said. “He had played incredibly well in Munich.” The Italian's 13-8 record for the year includes one title, but he could not replicate his Bavarian form on the Madrid clay.

Zverev's Historic Clay-Court Milestone

The win was Zverev's fourth Madrid semifinal, a tournament where he lifted the title in 2018 and 2021 and lost the final to Carlos Alcaraz in 2022. With the victory, he surpasses Mischa Kohlschreiber's record of 178 clay-court wins to become the all-time leader among German men in the Open Era. Zverev has now reached the semifinals at each of the first four Masters 1000 events of 2026 – alongside Jannik Sinner, the only player to achieve that this season. His 20-6 record on the year in six tournaments includes no titles, but his consistency in the biggest events remains formidable.

Semifinal Lineup Set in Madrid

Zverev will face Belgian Alexander Blockx in the semifinals, after Blockx defeated Casper Ruud. The other semifinal will be contested by Jannik Sinner and Arthur Fils, both matches taking place on Friday. On the women's side, Marta Kostyuk advanced to the final by defeating Anastasia Potapova 6-2, 1-6, 6-1, extending her winning streak to 11 matches. She will face Mirra Andreeva, against whom she has a 100% record after beating her earlier this year.

What Comes Next for Both Players

Zverev, now 20-6 on the season, will look to add a third Madrid title to his resume when he takes on Blockx. Cobolli, who has gone 13-8 in nine tournaments this year and won one title, will exit Madrid with a quarterfinal finish that includes a notable win over Medvedev. The Italian's defeat in the quarterfinals leaves him with work to do on clay ahead of the French Open, where he will aim to build on his breakthrough season. For Zverev, the path to a potential third Madrid crown runs through Blockx and then either Sinner or Fils.
