The 19-year-old made a big impression last year, particularly at the French Open, where he became the youngest quarterfinalist in the men’s singles event since Novak Djokovic in 2006.
Sinner has also been likened to Roger Federer with the tennis icon singling out the teenager for praise last year.
“What I like about him [Sinner] is he’s almost got the same speed of shot on forehand and backhand,” Federer said. “Similar to Felix [Auger-Aliassime] and some other guys.
“Back in the day – like Steve Johnson today you go to the backhand, you know it’s going to come back slower, go to the forehand and it will come back faster.”
