The 2018 and 2021 champion was better than Flavius Cobolli with 2:0 - 6:1, 6:4.
The German thus took revenge on the Italian for the recent defeat in Munich, also in the same stage of the tournament.
Zverev was simply too strong for Koboli today, and the direction this match would go could be predicted after about twenty minutes, when the scoreboard showed 5:0 for the third tennis player on the planet.
The second set saw a slightly bigger fight, with Koboli neutralizing six break points in two different games, but giving in at 4:4 – Zverev made a break, and then in the next game saved two consecutive break chances and advanced to the semifinals with four points in a row.
There he was defeated by Belgian Alexander Bloks, who had earlier eliminated defending champion Kasper Ruud.
In the second semi-final, Janik Siner and Artur Fiss meet.
