How would you do trying to guess the autographs of the best players on the ATP Tour?

Andrey Rublev, Alexander Zverev, Hubert Hurkacz, Alejandro Davidovich Fokina and Thanasi Kokkinakis gave it their best shot in the newest edition of the ATP Head-To-Head Challenge.

“This is not even a signature, No. 3,” Rublev said, cracking a laugh. “When the pen is not working, you try to make it [until], ‘Okay now it’s working’.”

“Is this person very good?” Kokkinakis asked about one autograph’s owner. “Is it Alcaraz? That’s not Zverev? Medvedev? Tsitsipas? Sinner? Is that Novak’s?”

One of the funniest moments of the feature came when Rublev made his guess for one of the autographs only to be told he was incorrect. After the 25-year-old made several more guesses, he was adamant that the signature belonged to the first player he guessed.
