Sinner dominated Altmaier 6-0, 6-2 in the first round of the Vienna Open.

There was no room for surprises at the Vienna Open. Two years after his dramatic comeback defeat to Daniel Altmaier at Roland Garros, Jannik Sinner returned and solved the German problem in less than an hour. On the indoor hard court, the Italian won 6-0, 6-2, displaying coolly precise tennis: 95% of points from first serve, 12/12 points at the net, and five breaks from six opportunities.

Match progression: Set 1 destruction, Set 2 control.

Altmaier had previously defeated Sinner at Roland Garros in 2022 after five sets, but that was his only victory against this opponent, and it came on clay. In their rematch on an indoor hard court, the scenario was completely reversed.

In Set 1, Altmaier opted for a safe approach, waiting for Sinner to make mistakes. However, the Italian player orchestrated the game perfectly and dictated the pace right from the serve. He broke Altmaier's serve three times in a row, had two clean service games, and closed out the set with a 6-0 victory.

Set 2 was not much different. Altmaier lost two more breaks, only won two games, and then accepted defeat 2-6. The difference in the quality of Sinner's first serve and his ability to transition to an attacking state made it impossible for the German player to catch up.

Tactical analysis: serve, one-touch shot, and net approach.

Sinner's 95% first-serve winning percentage (compared to Altmaier's 54%) demonstrates his complete control over the opening shots. Although his first-serve winning percentage was only 61% (Altmaier's 58%), every time the first serve appeared, Sinner turned it into an advantage with a clean "serve + 1" shot: returning the ball deep into the corner, forcing his opponent behind the baseline, and finishing with a winner or advancing to the net.

The standout tactical move was Sinner's ability to cut short Altmaier's waiting game. Altmaier played safely, waiting for errors from the baseline, but Sinner gave him virtually no chance: only 3 unforced errors throughout the match, and winning 77% of his second serves. Every time Altmaier attempted to change the direction of his attack, Sinner responded with deep, powerful return shots, forcing Altmaier into a defensive position.

At the net, Sinner's 12/12 performance is a testament to his proactive approach and ideal timing. He doesn't rush the net haphazardly but instead advances after a powerful shot, closing the gap and finishing cleanly. In contrast, Altmaier's 6/11 at the net reflects situations where he was drawn into a defensive position and had to hit the ball from difficult angles.

Altmaier was completely outmatched in terms of passing and ball transitions.

Altmaier failed to create any break opportunities (0/0 break points), while facing constant pressure in his service games. Only 21% of his points came from second serves, forcing him to take risks in short rallies, leading to an unsustainable match. In total, Altmaier had 9 winners, half the number of Sinner's 18, and couldn't compensate for this by forcing errors, as Sinner only made 3 unforced errors.

Key statistics

Impact and forward

The emphatic victory propelled Sinner into the second round, where he will face compatriot Flavio Cobolli. If the Roland Garros match two years ago showed Altmaier could draw Sinner into a sustained race on clay, this rematch confirms the difference on the indoor hard court: fast-paced rallies, effective serves, and the ability to finish points early have brought Sinner back to his familiar form.

With his near-perfect serving and conversion rate (5/6 breaks), Sinner has laid the groundwork for a promising campaign in Vienna. Altmaier, meanwhile, needs to rediscover his proactive approach on second serves and increase his return pressure if he wants to turn the tide in subsequent matches.
