Pundit tips Sinner for Slam success ahead of season opener

Italian Jannik Sinner's climb towards the top of men's tennis could hardly be described as sluggish unless of course a direct comparison is made with Spanish phenomenon Carlos Alcaraz.

While 20-year-old Alcaraz has exploded onto the scene in astonishing fashion and already has two Grand Slam titles under his belt, Sinner's progress has been less spectacular.

In the 16 Grand Slams the 22-year-old Sinner has contested, his best run was at last year's Wimbledon, where he reached the semifinals and was defeated by Novak Djokovic.
