Turns out that one of Pete Alonso’s biggest fans works in The Bronx.

Aaron Judge recently told The Post that during the Subway Series at Citi Field, he was quick to praise Alonso at first base because of the phenomenal rookie season Alonso is putting together for the Mets.

Big hitters appreciate other big hitters.

When asked about the conversation, Alonso said it was thrilling to hear such praise from the Yankees superstar, who blasted a rookie-record 52 home runs in 2017. Alonso will carry 37 home runs into the Mets’ key three-game series with the Nationals beginning Friday night at Citi Field.

“He said, ‘I hope you beat my record,’ ” Alonso told The Post of that conversation. “He said, ‘I love what you are doing, I really appreciate your play, keep doing it, man.’ ”

Alonso said to hear such encouraging words from Judge meant something special.

“It’s cool,” Alonso said. “Me and him are kind of in a similar type boat, just college guys people were kind of scratching their head: ‘OK, we got this big guy. He can do something in the minors, but we don’t know if it is going to translate because he is a right-handed power guy, there is just kind of a lot of similar questions. Can he play defense? Can he do this? Can he do that? Is he more than a DH?’

“I identify with all that because me and him both had to answer the bell, and he plays an awesome right field and I feel like I’ve come a long way at first base. I guess there are similar biases. It’s not like we were some sort of sexy, toolsy prospect. I feel like me and him had to overcome a lot of similar hurdles.”

And now to have big home-run success in the same city is such a great NY, NY story.
