This one is close. Sinner has been the cleaner ball-striker off both wings this season, and his first-serve numbers give him free points when he needs them. But Alcaraz owns the advantage in movement and variety, and their recent meetings have gone the distance. Expect a long, high-quality match that likely turns on a couple of break points.

Absolutely. His Grand Slam record speaks for itself, and best-of-five is where his return game and stamina still matter most. On the right surface he is a threat to anyone, and no top seed wants to see him across the net in the second week.
