Alcaraz's US Open Title Is More Improbable Than Raducanu's," Says Isner

John Isner offered a unique analysis: according to him, Carlos Alcaraz's run at the 2025 US Open surpasses Emma Raducanu's feat in 2021.

On one hand, Emma Raducanu, the surprise heroine of the 2021 US Open, came through qualifying and was crowned without dropping a single set. On the other hand, Carlos Alcaraz, an already established star on the tour, dominated the 2025 US Open by surrendering only one set, in the final, against world number one Jannik Sinner.

For John Isner, a former world top 10 player, the choice is clear. These remarks were made on the podcast "Nothing Major."

"I find what Alcaraz did more impressive. These are two comparable titles. But what Alcaraz did is more improbable. Even though Raducanu's story was truly remarkable, in terms of pure level, what Carlos did is even crazier, judges Isner.
