The two best men's players in the world are reconfiguring the sport before their opponents' eyes. They don't know what to do about it

The top-ranked Sinner, who is the defending champion at Melbourne Park, and No. 3 Alcaraz are coming off a 2024 season in which they each won two Grand Slam titles.

Carlos thinks about Jannik every time he practices, targeting further improvements for their upcoming encounters. Alcaraz also uses Sinner's titles and incredible success in the previous season to practice even harder and seek the extra gear that can make the difference.
