In a stunning turn of events at the ATP500 Halle Open, defending champion and world No.1 Jannik Sinner suffered a shock defeat in the second round. The Italian top seed fell to Kazakhstan’s Alexander Bublik (world No.45) with scores of 6-3, 3-6, 4-6, marking one of the biggest upsets of the grass-court season.
This victory represents a career milestone for Bublik, as it’s his first-ever win against a reigning world No.1 player. The Kazakhstani player demonstrated remarkable resilience after dropping the first set, ultimately securing his spot in the quarterfinals after two hours and four minutes of intense play.
Bublik’s impressive performance featured 15 aces and a 75% first-serve win percentage, while Sinner struggled with uncharacteristic errors, particularly on his backhand side. The match saw several momentum shifts, with Bublik breaking Sinner’s serve twice in both the second and third sets.
In the quarterfinals, Bublik will face seventh seed Tomas Machac of the Czech Republic, who advanced after a straight-sets victory over his opponent. This unexpected result shakes up the Halle Open draw and raises questions about Sinner’s preparation for Wimbledon, which begins in two weeks.
The tennis world has reacted with surprise to this early exit by the reigning Australian Open champion, with many analysts noting that Sinner had been considered one of the favorites for both the Halle title and the upcoming Wimbledon Championships.
