Jannik Sinner kick-started his Erste Bank Open campaign in striking fashion on Wednesday, when he soared past Daniel Altmaier 6-0, 6-2 to record his quickest victory of 2025.
The top seed and 2023 Vienna champion overwhelmed Altmaier from the outset with his heavy ballstriking and imposing pace, racing to the finish in just 58 minutes. Sinner, who was forced to retire from the third round of his Shanghai title defence earlier this month, extended his winning streak on indoor hard courts to 17 matches.

“I feel like in the first set everything was working very well,” said Sinner. “On indoor courts, you have to be very careful. If your opponent starts to serve well, it’s very difficult to break. But I’m very happy about today’s performance, starting the tournament in a very positive way, not only gamewise but feeling wise.”
Sinner’s previous fastest win of the season came in his opener in Cincinnati, where he blitzed Daniel Elahi Galan in 59 minutes. Against Altmaier at the ATP 500 event in Vienna, the 24-year-old Italian hit 19 winners to just seven unforced errors and did not face a break point, according to Infosys ATP Stats.
After improving to 29-0 in the opening rounds since Cincinnati in 2023, Sinner will next meet countryman Flavio Cobolli, who moved past Tomas Machac 7-6(6), 6-2.
Watch Extended Highlights from Wednesday's action:
Last week’s Almaty champion Daniil Medvedev overcame Nuno Borges 6-4, 6-7(7), 6-2 to keep alive his late-season push to qualify for the Nitto ATP Finals. After letting slip two match points in the second-set tie-break, Medvedev regrouped in impressive fashion to begin his title bid in Vienna, where he last lifted the trophy in 2022.
The former Nitto ATP Finals champion is 13th in the PIF ATP Live Race To Turin and could meet eighth-placed Lorenzo Musetti in a blockbuster quarter-final clash in Vienna. First, Medvedev faces a rematch of the Almaty final against Corentin Moutet, who earlier eased past qualifier Damir Dzumhur 6-3, 6-0.
Matteo Berrettini, the 2019 Vienna semi-finalist, opened centre court action on Wednesday with a 7-6(5), 6-3 win over Alexei Popyrin. Standing in the Italian’s way of a fourth consecutive quarter-final at the ATP 500 event is Cameron Norrie, whom he leads 2-0 in their Lexus ATP Head2Head series.
The winner of their clash will face third seed Alex de Minaur, who defeated Austrian wild card Filip Misolic 6-4, 6-4 in the last match of the day. De Minaur, who is into his 11th tour-level quarter-final of the season, leads the ATP Tour with 39 hard-court wins in 2025. He is seventh in the PIF ATP Live Race To Turin and aiming to hold off other Turin chasers this week as he bids to capture his second ATP 500 title of the year after Washington.
Earlier, Tallon Griekspoor became the first Vienna quarter-finalist by edging Brandon Nakashima 7-6(4), 7-6(2) with a clutch display. He awaits second seed Alexander Zverev or qualifier Matteo Arnaldi.
