Ben Shelton beats Jannik Sinner in quarter-finals

Shanghai: Ben Shelton advanced to his first Masters quarterfinal by beating fourth-ranked Jannik Sinner 2-6, 6-3, 7-6 (5) on Tuesday.

The 21-year-old American, a semifinalist at the U.S. Open, had 15 aces as his serve improved throughout the match.

“I had a lot of belief in my ability to serve and hang tough and to make it deep in sets,” Shelton said. “My serve wasn’t working that well in the first set, I felt that he was really on top of me. I really started to find my groove and had one of my best serving days in the second and third sets.” The 19th-seeded Shelton will next play Sebastian Korda, who advanced to his second Masters quarterfinal with a 7-5, 7-6 (6) victory over Francisco Cerundolo.
