For the past two years, the Grand Slam titles have been a tug of war between Carlos Alcaraz and Jannik Sinner, each claiming two majors per season. Now, post–US Open, the big question is: who’s next to break this “Big Two” grip on Slams? Quick recap of the rivalry: This was their third straight Slam final in 2025, something never seen in the Open Era. They’ve split the last eight majors, dominance reminiscent of past duos like Nadal–Federer or Borg–McEnroe. With his U.S. Open win, Alcaraz is back to World No. 1 with six Slams to Sinner’s four. Who’s coming for the crown? The veterans: Novak Djokovic is past his prime but still dangerous on the Slam stage. Daniil Medvedev’s consistency and Zverev’s big-game ability keep them in the mix. The rising challengers: Felix Auger-Aliassime is back in Slam semifinals form. Holger Rune is climbing again with wins over top names. Lorenzo Musetti’s flair and versatility keep him intriguing. And 18-year-old João Fonseca looks like Brazil’s next great hope. So, will Alcaraz and Sinner keep their stranglehold on the majors — or is it only a matter of time before one of these names breaks through? #USOpen #Tennis #Alcaraz #Sinner #AugerAliassime #Rune #Musetti #Fonseca #Sports
