Jannik Sinner continued his superb 2025 season with a commanding straight-set victory over Alexander Bublik to reach the semi-finals of the Vienna Open.
The world number two, who has reached all four Grand Slam singles finals this year, was near flawless on serve as he dispatched Bublik 6-4, 6-3 in just 76 minutes. A single break of serve in each set was enough for the Italian to secure his 60th win of the season and move a step closer to his fourth ATP title of the year.
Sinner, 24, has now won 19 consecutive matches on indoor hard courts and remains unbeaten in Vienna since lifting the title in 2023. His form indoors has been near untouchable, built on a combination of ruthless baseline power and relentless consistency.
“Every match is tough, but I feel good and I’m trying to stay aggressive,” Sinner said after the win. “Alexander is a difficult opponent because he mixes up his shots a lot, so I’m happy with how I managed the key points.”
Bublik, ranked 16th in the world, had beaten Sinner earlier in the year in Halle, but this time found himself overpowered from the very first game. The Kazakh was unable to find rhythm on return as Sinner lost just five points on serve throughout the match and never faced a break point.
The Italian also made the most of his chances, converting two of eight break points while applying constant pressure on Bublik’s second serve.
With the victory, Sinner advances to face Australia’s Alex de Minaur in Saturday’s semi-final. De Minaur booked his spot by defeating Matteo Berrettini 6-1, 7-6 (7-4), earning his 53rd win of the season — the second-highest total on the ATP Tour behind world number one Carlos Alcaraz.
De Minaur and Sinner last met in the 2024 ATP Finals group stage, where the Italian triumphed in straight sets. Their upcoming clash promises to be another test of Sinner’s indoor dominance against one of the game’s quickest and most resilient defenders.
Sinner’s remarkable 2025 campaign has seen him collect Grand Slam titles at the Australian Open, Wimbledon, and the US Open runner-up trophy after losing to Alcaraz in a thrilling five-set final. The Italian’s consistency has made him a fixture at the top of the men’s game, though his brief stint as world number one ended after that US Open defeat.
Still, his record since last year has been extraordinary — winning 60 of his past 66 matches — and he remains among the favourites heading into next month’s season-ending ATP Finals in Turin.
Elsewhere in Vienna, German world number three Alexander Zverev advanced to the semi-finals without hitting a ball after Dutch opponent Tallon Griekspoor withdrew due to injury. The walkover ensures Zverev joins Alcaraz, Sinner, and Novak Djokovic as the first four players to qualify for the ATP Finals.
Zverev will now face either Italian fourth seed Lorenzo Musetti or France’s Corentin Moutet for a place in the final.
For Sinner, however, all focus is on maintaining his momentum and closing out another dominant indoor campaign. “I just want to finish the season strong,” he said. “It’s been a great year, and I’m enjoying every moment on court.”
With his confidence soaring and his serve firing, Sinner looks poised to add another title to what has already been a defining year in his young career.
