Mike Piazza was back in Queens on Monday, remembering not just the Sept. 11 terrorist attacks, but his dramatic home run 10 days later against the Braves in the first game back in New York City.

And just like in that game, the Mets once again were wearing hats from the FDNY and NYPD on Monday at Citi Field.

“We made a statement we wanted to wear the hats and it’s something at the beginning that we got some pushback on,” Piazza said of the first game back. “We were willing to pay the fine. We didn’t care. No one was gonna take those hats off us.”

He’s not surprised that legacy has continued.

“This is part of who we are as an organization,” Piazza said. “I’m sure with the Yankees and the [local] football teams, as well. It’s part of who we are. It will always be a part of us. Fifty years from now, I know this organization is gonna honor 9/11, because it affected us personally.”

Pete Alonso has been among the current Mets who has made sure that’s remained the case.

On Monday, the first baseman wore cleats that represented the organization “Answer the Call,” which provides financial support to families of first responders killed in the line of duty.

“He’s shown leadership in that realm,” Piazza said of Alonso. “He’s taken it upon himself to show that performance on the field is important, but you are part of the community. He’s taken it upon himself in a very authentic way. It’s true leadership.”

Piazza, along with former teammates including John Franco and Todd Zeile, still visit local fire departments around the anniversary of Sept. 11 and they did so again recently.

As for his memorable home run that gave the Mets the lead in the eighth inning, Piazza said, “At that point, I don’t think the results of the game really would’ve mattered. It’s just the story unfolded [that way] and made it more exciting.”
