Jannik Sinner dropped a set for the first time this week in the third round victory against Denis Shapovalov.

After escaping from a deuce game midway through the second set, Sinner broke Shapovalov for a 4-3 lead and won two more games to level the match.

Sinner landed 58% of first serves in play and won 84% of first serve points (54/64). Sinner won 50% of second serve points (23/46) and saved three of six break points.

Jannik Sinner vs Alexander Bublik Prediction

Laying the games here. Sinner’s level on hard courts has been exceptional, such that losing a set to Shapovalov in the last round felt like a mini upset in itself. No player can accelerate and strike a cleaner ball than the World No.1 right now. Bublik is undefeated in 11 matches and beat Sinner when they last met in Halle. But Bublik is Bublik. He’s one of the most mercurial players on tour and can be erratic in an instant. He’ll be competitive for at least a set and a half and likely wilt. Sinner should easily make it to the last eight.
