The Mets wore NYPD hats and held a moment of silence before Tuesday night's game against Baltimore to honor a police officer who was shot and killed this week while on duty.
Officer Brian Moore died Monday, two days after he tried to stop a man suspected of carrying a handgun.
"It's part of what we think is important and certainly, honoring Officer Moore is important today and so we are wearing them and wearing them with pride," Mets manager Terry Collins said.
The Mets and Orioles lined up for the tribute. Police officers stood next to the teams and Moore's picture was shown on the scoreboard.
The 25-year-old Moore was the son, nephew and cousin of police officers. He was a fan of the Orioles, and manager Buck Showalter said the officer's favorite player was slugger Chris Davis.
Davis signed a ball and Showalter said the team would autograph an Orioles home jersey for the family.
"We were going to do a jersey today, but we're going to overnight a white jersey. We thought he and his family would have liked that," Showalter said.
"I think he was at one of the playoff games last year," he said.
Showalter said Moore's death "makes you just think about their families and the whole thing, how much those men and women are in harm's way every day for us."
"When you listen to a lot of people talk about him, he was pretty special," he said.
The Mets wore their regular caps during the game.
Moore, a Long Island native, will be laid to rest Friday. A procession accompanied his body to the Frank J. Chapey and Sons Funeral Home in Bethpage Tuesday.
Thousands attended a vigil for him Monday night, and a memorial outside the 105th Precinct stationhouse in Queens Village continued to grow.
