Jannik Sinner says what he’s noticed about Taylor Fritz’s serve at the ATP Finals after a practice session together

Jannik Sinner began his ATP Finals in perfect fashion as the home favourite beat Alex de Minaur 6-3, 6-4.

Sinner trained with Radek Stepanek before the ATP Finals, with the Italian looking to go one better than his runner-up spot last year.
He lost to Novak Djokovic in last year’s final, but is now the world’s top player in Turin, much to the delight of the supporters.

A reunion is, of course, off the cards this time around, with Djokovic having withdrawn from the ATP Finals with injury.

Sinner could, however, meet his new rival Carlos Alcaraz in the final, although he does need to make it out of a tough group first.
