Alex de Minaur (AUS/3) vs. Matteo Berrettini (ITA) – Starts at 1:30 p.m.
So far, Alex de Minaur has faced only Austrians in Vienna. After defeating Jurij Rodionov in the opening round, the Australian also beat Filip Misolic in straight sets in round two. Now he faces Italy’s Matteo Berrettini, who booked his spot in the last eight after a marathon 3-hour-16-minute battle against Cameron Norrie.
Tallon Griekspoor (NED) vs. Alexander Zverev (GER/2) – Not before 3:00 p.m.
Tallon Griekspoor’s round-of-16 win over Brandon Nakashima came in straight sets, though both were decided in tense tiebreaks. Alexander Zverev, on the other hand, was all business: after needing three sets in his opener against British qualifier Jacob Fearnley, the 2021 Vienna champion dispatched another qualifier, Italy’s Matteo Arnaldi, in less than 90 minutes. Zverev leads their head-to-head 8–2 but remains cautious: “It’s always been close,” he said. “He’s one of those players who always raises his level against top opponents — he even beat Sinner this year.”
Jannik Sinner (ITA/1) vs. Alexander Bublik (KAZ) – Not before 5:30 p.m.
Alexander Bublik has been flying under the radar but delivered impressive performances, spending just over two hours on court across his first two rounds. The Kazakh has transformed from a streaky shot-maker into a genuine winner, capturing four titles in 2025 — on clay, grass, and hard court. Across the net awaits top seed Jannik Sinner, one of the game’s dominant forces. Sinner raced through his opener against Daniel Altmaier in just 58 minutes, before being pushed harder by Flavio Cobolli, who forced a tiebreak in the second set. Sinner and Bublik have met three times this year — the Italian won at the Grand Slams in Paris and New York, while Bublik prevailed on grass in Halle. Overall, Sinner leads the head-to-head 5–2.
Corentin Moutet (FRA) vs. Lorenzo Musetti (ITA/4) – Not before 8:15 p.m.
The final match of the day brings together two contrasting styles. France’s Corentin Moutet, the creative “rising star” known for his unorthodox tactics — forehand slices, underarm serves, and plenty of flair — has already frustrated Daniil Medvedev in the previous round. Facing him is Italy’s Lorenzo Musetti, a true stylist of the game and one of the few players on tour still wielding a one-handed backhand. Their only previous meeting came earlier this year in Buenos Aires, where Musetti claimed a straight-sets win on clay.
