Yankee Stadium will install metal detectors at select entrances starting Tuesday, and will have them at all gates in 2015 to conform to MLB rules.

The team said the move was to "acclimate staff and fans to the new procedure."

"Due to the enhanced security measures," the team said in a statement, "the Yankees strongly urge all fans to begin budgeting extra time for entry into the ballpark when planning their trip to the Stadium."

Fans will be asked to remove cell phones and all metal objects from their pockets before entering, the Yankees said.

Keeping up with league standards, bags 16 inches x 16 inches x 8 inches or smaller will be admitted, the team said.

Those who don't want to go through a walk-through metal detector have the option to be checked with a hand-held detector.

“Nothing is more important to us at Yankee Stadium than the safety of the fans we serve,” Yankees Chief operating officer Lonn Trost said in a statement. “To that end, we are committed to the procedures that Major League Baseball and the Department of Homeland Security have asked us to implement. We want our fans to feel safe in Yankee Stadium, and our staff is dedicated to maintaining the highest security standards possible.”
