Alexander Zverev hosts Alex de Minaur on Centre Court in Vienna for their ATP semifinal at the Erste Bank Open. Both players have reached the final four without their matches yet decided, with the German serving first on the main showcourt. The winner advances to Sunday's final, where the next opponent will come from the opposite half of the draw. De Minaur, the 2024 US Open finalist, has won his last three meetings with Zverev on hard courts. The 60-minute session begins at 11:30 AM EDT, with both players looking to claim their first title at this event.
