The Mets wore NYPD caps during batting practice Tuesday to honor fallen police officer Brian Moore, the Massapequa, N.Y., native who died Monday after being shot Saturday in Queens. Moore, 25, worked less than 10 miles from Citi Field.

“Somehow, someplace along the line, hopefully we don’t have to keep wearing these hats,” Mets manager Terry Collins said. “We are honoring the true heroes — the soldiers, the police, the fire department — who keep us all safe and secure. It’s sad to think we’ve got to wear them.

“It’s what we think’s important, and certainly honoring Officer Moore is important today. We’ll wear them and wear them with pride, and hopefully his family understands — although it’s hard to understand what they’re going through — that we’re there for them.”
