Jannik Sinner vs. Alexander Bublik Head to Head, Prediction and Betting Odds for ATP Terra Wortmann Open 2025 Round of 16

2023 vs 2024 Halle Open champion on OWL Arena.

Jun 4, 2025; Paris, FR; Jannik Sinner of Italy at the net with Alexander Bublik of Kazakhstan after their match on day 11 at Roland Garros Stadium.

“I almost got him guys,” said Alexander Bublik after losing to Jannik Sinner in straight sets at the recent French Open 2025. It will be a quick turnaround for the duo, as Sinner and Bublik will renew their rivalry at the 2025 Terra Wortmann Open in Halle. The winner of this match will face either Tomas Machac or Fabian Marozsan in the quarterfinals.

The No. 1 player in the world at the moment, Jannik Sinner suffered a heartbreaking loss in the Roland Garros final. He will be looking to avenge his maiden Grand Slam summit clash loss by capturing the Wimbledon crown this year. Sinner has recorded an 18-2 run this season, with both losses coming against Carlos Alcaraz. The 23-year-old overcame home favourite Yannick Hanfmann in Round-1.

“He’s a great, great player,” said Sinner about ‘Sascha’ Bublik ahead of this encounter. The Kazakh powerhouse reached his maiden Grand Slam QF at Roland Garros in 2025. He is a former Halle champion (2023), where he beat Sinner en route to the title. 27-year-old Bublik is yet to face a break point on grass this year – he comfortably stormed past Alexandre Muller of France in the Round of 32. The former Top-20 star has an 11-14 record this season.

Jannik Sinner vs Alexander Bublik Head to Head Record

Jannik Sinner has a 4-1 head-to-head record against Alexander Bublik of Kazakhstan. Bublik’s only win was at Halle in 2023.

Sinner and Bublik were on collision course during the 2021 Dubai Duty Free Tennis Championships, when the Italian came back from a set down to beat Bublik. He went on to cruise past the 6’5” giant in straight sets over their next two meetings, before retiring from their Halle 2023 quarterfinal. At the French Open this year, the top seed returned to winning ways in style.

Jannik Sinner vs Alexander Bublik ATP Halle Open 2025 Prediction

Considering the state of affairs on the ATP Tour, the Halle Open is possibly Bublik’s best shot at defeating Sinner. The courts are fast, beneficial for strong servers, and he has the experience of lifting the trophy here previously. With the courts playing slightly faster than Wimbledon, variety will be the key for him to dismantle the World No. 1’s flawless baseline wrath. But having gotten crucial game time in the opening round, Sinner is likely to unleash his best level.

Prediction: Jannik Sinner in straight sets.

These two Halle kings meet again. 👑
