World No.1-bound Alexander Zverev stunned by Alex de Minaur in Vienna Open semi-final

Alexander Zverev's first match as the incoming world number one ended in a surprise defeat, as Australia's Alex de Minaur pulled off a straight-sets victory in the Vienna Open semi-finals on Saturday. The German, who will officially top the ATP rankings on Monday, was beaten 6-3, 6-4 in just 71 minutes, failing to convert any of his three break points. De Minaur, ranked 10th, was clinical on serve and aggressive from the baseline, handing Zverev only his second loss in his last 15 matches. The result raises questions about whether the pressure of the top ranking is affecting Zverev, who had been in stellar form with titles in Chengdu and Tokyo. For De Minaur, it marks his first win over a world number one and a second consecutive final in Vienna. Zverev will now head to the Paris Masters as the top seed, while De Minaur faces Jannik Sinner or Daniil Medvedev in Sunday's final, with a chance to claim his biggest indoor title yet.
