Jannik Sinner vs Daniel Altmaier Match Preview
Jannik Sinner is a serial winner, and one of the most dominant forces in men’s tennis at the moment. The 24-year-old is particularly a beast on the hard courts – which he has proven with successes at the Australian Open, China Open and Six Kings Slam. The top seed in Vienna also won his first Wimbledon trophy this year, beating rival Carlos Alcaraz in the final. A four-time Grand Slam champion, Sinner has a practically flawless 43-6 record in 2025. When it comes to his hard court statistics this season, he has won 80% points on first serve and 92% service games.
Daniel Altmaier is currently ranked just outside the Top-50 at No. 51 in the world. The German sensation reached consecutive quarterfinals at the Rotterdam Open and Open 13 in February. Despite impressing with a Round of 16 appearance at Roland Garros and several other pre-quarterfinal finishes, Altmaier has not been able to make it to the final stages of events. This has left him with a win-loss record of 18-25 this year. The 27-year-old has saved 60% break points and converted 34% break points on hard courts throughout the year.

Jannik Sinner vs Daniel Altmaier ATP Vienna Open 2025 Prediction
Last week in Riyadh, Jannik Sinner was arguably in the best form of his season. The reigning champion won the Six Kings Slam without dropping a set, and had all bases covered. The return of serve in particular was flawless – he was taking the ball very early and giving his opponents no time to dictate play. Altmaier will need to paint the lines in order to stand any chance against Sinner in Vienna. Yet, the 2023 champion is the firm favorite.
Prediction: Jannik Sinner in straight sets.
