Andrey Rublev dishes on "responsibility" in new role as godfather to Daniil Medvedev's daughter

WATCH: Tennis Channel Live discusses the refreshing honesty from Andrey Rublev in era of sports where athletes are trained to often give robotic answers.

World No. 6 Andrey Rublev won hearts the world over during this weekend at the Rolex Monte Carlo Masters—both for the way he fought back to defeat Holger Rune 5-7, 6-2, 7-5 in the final, and for his hilarious honesty in interviews throughout the tournament.

After lifting his 13th ATP trophy—and his first at the Masters 1000 level—on Sunday, Rublev kept the laughs coming as he opened up his new role as godfather to countryman Daniil Medvedev’s six-month old daughter, Alisa.

“Godfather” is more than just a title, Rublev said, speaking to Championat’s Sofia Kolodkina after the match—and apparently, it comes with an unexpected set of responsibilities:

“The priest made such a speech [about my duties] that I even said: ‘What should Danya do then, since I have to do all of this?’ To which the priest said that Daniil must support his family financially,” the 25-year-old recalled.

“I asked him if it was possible to switch, because it looks like I have many times more responsibility than Dani!”

“Now I am responsible for making sure she believes in God,” he elaborated. “I also have to pray for her every day, make sure that she does not take off her cross, and also make sure that she grows up as a good and kind person!”

A good and kind person? It seems that Alisa is in great hands, in that case, with Rublev earning a reputation for being one of the nicest guys on tour. For further proof, just check social media to see the way fellow pros congratulated him on his first Masters 1000 victory.

Rublev’s authenticity is a quality that Andy Roddick applauded during a Tennis Channel Live segment—as he highlighted the sport’s need for new and engaging personalities in a conversation with Chris Eubanks and Brett Haber.

“Every time he speaks, it is so raw and and as a player, it's relatable,” Roddick said. “I think we [professional athletes] all put forward this false bravado a lot of times. For our own protection, whatever it is, we try to create a certain narrative around ourselves, but it just does not seem like he cares. He just wants to tell us what he thinks.

"The way he ebbs and flows during interviews… This is just great. Every time he talks, I find myself laughing."

Despite clinching his biggest title to date in Monte Carlo, there are no days off for the Russian who is already preparing to defend his title at an ATP 250 event in Banja Luka, Bosnia-Herzegovina (previously Belgrade).

Rublev, the No. 2 seed, awaits the winner between Juan Pablo Varillas and Hugo Gaston in the second round.
