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.

For years, tennis fans were spoiled by the golden era of the Big Three — Roger Federer, Novak Djokovic and Rafael Nadal — who didn’t just dominate the sport but also elevated each other to legendary heights every time they stepped on court.

Alcaraz kick-starts his quest for a maiden title at Flushing Meadows on Monday against Reilly Opelka, while Sinner faces Vit Kopriva 24 hours later
