The No. 5 seed fired 11 aces in his 6-3, 6-4 win against Nuno Borges. Five of Rublev’s 16 career titles have come on the ATP 500 stage.
Fourth seed Daniil Medvedev continued his quest to end a title drought dating back to May 2023 by routing Zizou Bergs, 6-2, 6-1. The former US Open champion capitalized on five of his nine break points for his 300th career hard-court win.
In the last eight, Medvedev faces Felix Auger-Aliassime. The Canadian, winner of two titles already this season, received a walkover from Hamad Medjedovic. The 21-year-old injured his hamstring in the prior round before valiantly battling through to eliminate Tsitsipas.
Eighth seed Jack Draper dispatched qualifier Christopher O’Connell, 6-2, 6-1, and gets either Matteo Berrettini or Tallon Griekspoor Friday.
