Jannik Sinner vs Alexander Bublik prediction

Jannik Sinner will face Alexander Bublik for the fourth time this year with the Kazakhstani underdog hoping to provide more of a test than in their last meeting. 

The Italian world number two dropped just three games as he rampaged to a 6-1 6-1 6-1 success at the US Open, leading Bublik to jokingly claim the four-time major winner was ‘AI.’

Overall, Sinner leads the match-up 5-2 with both of Bublik’s victories coming on grass at Halle.

The eighth seed has produced some exceptional tennis this season and has reached a career high, but even if his enigmatic ways help him to reach halcyon heights in this latest encounter, it may still not be enough against Jannik on an indoor hardcourt.

The top seed took under an hour to dismantle Daniel Altmaier and then brushed aside his compatriot Flavio Cobolli 6-2 7-6.

Against anyone else, Bublik would fancy his chances here, but with it being Sinner, the sheer power and relentless consistency will no doubt be too much once more.
