World No. 1 Jannik Sinner suffered a surprise defeat at the Halle Open on Thursday, falling in three sets to Alexander Bublik, 3-6, 6-3, 6-4, in the second round of the ATP 500 grass-court tournament.

A rematch of the 2023 Wimbledon final in the Berlin Tennis Open quarterfinals produced the same result: victory for Marketa Vondrousova over Ons Jabeur, this time by a 6-4, 6-1 scoreline.
