Defending champion Jannik Sinner kept his title defense on track by beating Jan-Lennard Struff 7-5, 7-6 (4), 6-3 to advance to the semifinals.
The top-ranked Sinner continues to put his French Open meltdown behind him.
He needed five sets to get past 50th-ranked Miomir Kecmanovic in the first round, but since then they’ve been straight-set victories, allowing the 24-year-old Italian to avoid marathon sessions.
Sinner will next face either seven-time Wimbledon singles champion Novak Djokovic or third-seeded Felix Auger-Aliassime.
The men’s final is on Sunday.
In the completion of a fourth-round match, second-seeded Alexander Zverez beat Jiri Lehecka 6-4, 7-5, 3-6, 7-6 (6) to set up a quarterfinal Wednesday against sixth-seeded Taylor Fritz.
