Anthony Causi, a highly skilled and popular sports photographer for the New York Post who covered the city's teams for 25 years, died Sunday from the coronavirus. He was 48.

The newspaper reported Causi's death on its website Sunday night and included an image of Monday's back page. It featured a photo of Causi holding a camera with a long lens and the words "Our Eyes, Our Heart'' and then below: "And our city's loss.''

Causi was married with two young children. Many of New York's professional teams and several players posted messages on Twitter expressing sadness, condolences and paying tribute to him.

"Do you know how many athletes reached out when they heard he was sick?'' said Stephen Lynch, editor-in-chief at the Post. "Players from every team, sending thoughts, hoping he was going to be all right.''

Major League Baseball called Causi a "sports photojournalist extraordinaire'' and said he "brought out the best in the players and the people of our National Pastime.''

Causi was a smiling and friendly fixture at venues such as Yankee Stadium and Madison Square Garden and others all over the New York area. His action shots often popped impressively on the Post's sports pages, and he was well-liked not only by media colleagues but also the famous players he chronicled.

"What a great man. So sorry to hear,'' tweeted Texas Rangers infielder Todd Frazier, who played for both the Yankees and Mets. "God found his angel photographer, that's for sure.''

Curtis Granderson, former Yankees and Mets outfielder, wrote: "New York baseball won't be the same without him in the photo pit.''

Philadelphia Phillies shortstop Didi Gregorius, who played for the Yankees from 2015 to '19: "Anthony was a great, funny and awesome guy to talk to and learn from about sports photography ... may he Rest In Peace.''

Lynch called Causi "a brilliant journalist.''

"He was, quite simply, one of the best sports photographers in New York City, capturing all the major moments of the past 25 years. Soft-spoken, funny, but most of all kind -- he was respected by those he photographed and admired by those with whom he worked,'' Lynch said.

"The Post that you read, and the newsroom that we work in, are less colorful today because of his absence. Our hearts go out to his family, and we share their grief.''

Causi, born and raised in Brooklyn, graduated from Pace University. He joined the Post in 1994 as a photo messenger before advancing to photo editor and then full-time journalist photographer, the newspaper said.

His uncle, Joe Causi, an on-air personality for WCBS-FM radio, said his nephew often took photos at Little League events pro bono, the Post said.

The Post said Causi is survived by his wife, Romina, and their children, John, 5, and Mia, 2, as well as his parents, Lucille and John Causi, and sisters Maria Marangelli and Dianna Marotto.
