Italy’s world number two, Jannik Sinner, advanced to the quarter-finals of the ATP Vienna Open after a hard-fought 6-2, 7-6 (7/4) victory over compatriot Flavio Cobolli on Thursday, October 23, 2025.
The top-seeded Sinner, a four-time Grand Slam champion, showed flashes of his trademark precision and power early on, breezing through the first set without facing a single break point. However, Cobolli, 22, demonstrated impressive resilience in the second set, forcing a tiebreak after fending off four break opportunities from his more experienced opponent.
Despite the late resistance, Sinner maintained his composure to close out the match in straight sets, securing his place in the last eight of the Austrian event. The win comes as a confidence boost for the Italian after he was forced to retire earlier this month during his third-round clash against Tallon Griekspoor at the Shanghai Masters due to cramps.
Reflecting on the victory, Sinner praised his fellow Italian’s fighting spirit and acknowledged the challenge of maintaining focus in tight moments.
“He is a great talent and a great competitor and we both played some great tennis at times,” Sinner said after the match. “I had some chances in the second but could not use them, and that is tennis. I tried to stay in the moment and play with a great mentality, and I am very happy with today’s match.”
Sinner will now face eighth seed Alexander Bublik in the quarter-finals after the Kazakh comfortably dismissed Francisco Cerundolo 6-4, 6-2. The matchup promises to be an exciting encounter, with Bublik’s powerful serve and unpredictable shot-making likely to test Sinner’s baseline consistency.
Elsewhere in Vienna, second seed Alexander Zverev also booked his place in the last eight, setting up a clash against Dutchman Tallon Griekspoor — the same player who benefited from Sinner’s retirement in Shanghai.
In another notable result, France’s Corentin Moutet avenged his recent loss to Daniil Medvedev by defeating the Russian 7-6 (7/3), 6-4. The pair had faced off just four days earlier in the Almaty final, where Medvedev triumphed.
With several top seeds still in contention, the Vienna Open quarter-finals are shaping up to deliver thrilling tennis as players battle for valuable points ahead of the season’s final stretch.
