Sinner, ranked at nine in the world, saved all eight break points he faced to clinch a tough 6-7 (4/7), 6-4, 6-4 second-round triumph.
“It was a tough match for sure. He had a lot of chances,” said Sinner after reaching his ninth quarterfinal of the year.
“I made a couple of mistakes in the tie-break but that can happen. On grasscourts it’s never easy, and the way I reacted, especially mentally, I guess I did a good job. Obviously playing against him is never easy.”
Sinner will next face Alexander Bublik who reached the quarterfinals with a 6-3, 6-7 (4/7), 6-3 victory against Germany’s Jan-Lennard Struff.
Bublik hit 43 winners, including 23 aces as he reached his second quarterfinal of the season.
