Like his photographs, Anthony Causi’s legacy lives on.

Causi, the heartfelt, charming and passionate Post photographer who died Sunday at the age of 48 after contracting the coronavirus, spent a quarter-century documenting New York sports through his lens.

Without him, the sidelines will never feel the same.

“Anthony Causi was a fixture at the Garden and one of the best photographers in the business,” the Knicks said in a statement. “He was a warm person with a great personality and will be missed. We send our deepest condolences to his family.”

To so many, Causi felt like family.

“He was a New Yorker. Anthony was passionate, he grinded, he cared and was caring, and he wore his heart on his sleeve. And it was a huge heart. I don’t know how it fit on his sleeve,” said Jason Zillo, Yankees’ vice president of communications and media relations. “People gravitated towards him, but he had an edge to him and he never wanted to have the second best photo of the day. On behalf of our entire organization, we will miss him and offer our heartfelt condolences to his family.

The Rangers fondly remembered the multi-talented photographer, too.

“Anthony was kind, thoughtful and one of the best at what he did. We are heartbroken to hear of his passing,” the statement read. “Our thoughts and prayers go out to his wife, Romina, and their children, John and Mia. You will be missed, Anthony, by all of us.”

Mets COO Jeff Wilpon also released a statement, on behalf of the team, as “RIP Anthony” trended on Twitter:

“We are deeply saddened to learn of Anthony’s passing. He was a charismatic photographer who brought fans closer to the action with his breathtaking images of the Mets. More importantly, he was a friend to so many of us through his numerous spring trainings in Port St. Lucie as well as being a fixture at Citi Field. Our heartfelt condolences go out to his wife, Romina, son John, daughter Mia and the entire family.”

While Causi earned the respect of countless athletes for his photographs and professionalism, the father of two also earned their affection with his gregarious personality.

“My condolences goes to The Causi Family. Anthony was a great, funny and awesome guy to talk to and learn from about sports photography … may he Rest In Peace,” former Yankees shortstop Didi Gregorius tweeted.

Todd Frazier became acquainted with Causi during stints with the Yankees and Mets.

“What a great man. So sorry to hear. God found his angel photographer that’s for sure,” Frazier wrote.

The Jets offered Causi an honor certain to make him smile.

“Cameras Up. Always.” the Jets wrote. “Rest In Peace Anthony. We will miss you.”
