Jannik Sinner vs Alexander Bublik prediction

Jannik Sinner made a winning start on grass in his first match on tour since his French Open final defeat. The Italian was always in control of his match against Yannick Hanfmann, winning 7-5 6-3. He now goes up against Alexander Bublik in the round-of-16.

Bublik, who won this event in 2023, didn’t even give up a break point as he defeated Alexandre Muller 6-4 6-4 in round one. It was a very strong serving performance from the Kazakhstani, who won 89% of his first serve points in his first match on grass this season.

Sinner leads the head-to-head 4-1 and won their most recent encounter in the quarter-finals of the French Open just a few weeks ago in straight sets. However they are 1-1 on grass with Bublik winning his only match against the Italian at this very event two years ago. Sinner was forced to retire after going a set and a break down in their quarter-final match.

Sinner has improved his fitness and made strides as a grass court player since that meeting. Though Bublik will be a good test for the world number one, he should still book his place in the last eight with a straight sets win.
