My prediction for the Sinner - Shapovalov match at the ATP Finals in Turin is a victory for Sinner. The Italian has been showing consistently high levels of play, winning his last seven matches in straight sets. I believe he will be able to secure the victory today. Furthermore, I expect the match to be quick, with both players scoring less than 20 games due to Sinner's dominance.
Jannik Sinner lost to Ben Shelton in the previous match, but this time, considering the form and level of play, I expect a victory for Jannik. Judging by his recent performances, he is in good form and ready to compete. Meanwhile, it will be difficult for Ben to replicate his success, given the advantage of experience and class on the part of the Italian. I expect a quick victory for Jannik. Therefore, I choose to bet on Jannik Sinner to win.
