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.
