Ahead of this year’s US Open, Carlos Alcaraz and Jannik Sinner have only reinforced their positions as the best two players in men’s tennis.

Alcaraz praises Sinner's level but also warns the Italian that he will 'have a big target on his back' at the US Open.

They'll still play the full U.S. Open starting Sunday in New York, but it might save some time to skip ahead to the men's final on Sept. 7.
