The fourth seed held off the powerful Lorenzo Sonego on Thursday for a 6-7(4), 6-4, 6-4 second-round triumph at the ATP 500. Sinner saved all eight break points he faced in an intriguing two-hour, 52-minute encounter inside OWL Arena to reach his ninth tour-level quarter-final of the year.

It was the second three-set win in a row on event debut for Sinner, who was pushed the distance by Richard Gasquet in his opening match. The 21-year-old will next play the winner between home favourite Jan-Lennard Struff and Alexander Bublik.
