How long can Bublik maintain his level of play?
An exciting quarterfinal awaits us in the Jannik Sinner vs. Alexander Bublik tip. The Kazakh is having the best season of his career – 16th place in the ATP world rankings and four titles are the well-deserved reward for his proven improvement in areas such as professionalism. His talent has never been in question.
On the other side of the net awaits one of the two dominant players of this tennis season: Jannik Sinner. The world number two has played a reduced schedule this season due to his suspension, without revealing any real weaknesses. We don’t want to question his favorite status in the Jannik Sinner vs. Alexander Bublik prediction anyway.
The best sports betting providers are in agreement. Jannik Sinner – Alexander Bublik odds are clearly colored in the colors of the Italian flag. Nevertheless, the Kazakh challenger can still harbor quiet hopes. The 28-year-old has already won a match against the South Tyrolean this calendar year.
Just like in 2023, Bublik won the head-to-head in Halle this season as well. After this victory, the Kazakh did not let the title in Halle slip away. It was to be one of four ATP triumphs in the 2025 calendar year – just as many as in his entire career before (4/8).
With his victory in Halle, Bublik is one of only three players to have defeated Sinner in an ATP-level match this calendar year. However, according to Jannik Sinner vs. Alexander Bublik betting odds, even winning one set in this eighth head-to-head match would be a surprise.
Jannik Sinner – Alexander Bublik Head-to-head record / H2H record
The South Tyrolean has won five of their seven encounters. As already mentioned, Sinner lost twice to his Kazakh opponent on grass in Halle (2023, 2025). The specific conditions in Vienna (an indoor hard court) suit both players.
Sinner brings a series of 18 wins in this specific environment to the quarterfinals. In addition, the 24-year-old has won seven of nine finals under these conditions in the course of his impressive career. He ended his last appearance at the Erste Bank Open with the title (2023).
Jannik Sinner – Alexander Bublik Tip
If Bublik is on form, he can challenge the world number two for a certain period of time. The Kazakh’s serves are daring, with incredible speed, and have helped him average 11.8 aces per match over the last 52 weeks (4th). On hard courts, the total is even higher (12.6 – also 4th in the comparison).
The 28-year-old is playful, likes to try little tricks, unsettling his opponents and breaking the rhythm of the game. If he uses this tactic successfully, he may be able to force Sinner into a prolonged adjustment phase.
However, Sinner is rightly the clear favorite. In the past two years, the 24-year-old has won 79 of his 85 matches on hard courts (four of the six defeats were inflicted by Carlos Alcaraz) and added two Grand Slam titles to his trophy cabinet this calendar year.
Nevertheless, Bublik’s talent level, his great serving skills, and his increased professionalism give a bet on “Alexander Bublik to win at least one set” a certain amount of value.
