Unlike at airports, fans can leave on their belts and shoes on when walking through the metal detectors. However, heavy metals, such as keys and loose change, as well as mobile phones, must be removed from pockets before passing through the stadium.
Additionally, laptops, selfie sticks, audio and video recorders, hard-shell bags and laser pens will not be permitted inside ballparks.
Fans who are unable to utilize a walk-through metal detector, or who opt not to use one, will either be check with a handheld metal detectors or receive a physical pat-down, the Associated Press reports.
Some teams, such as the Colorado Rockies, have created express lanes for fans without carry-in items. While the San Francisco Giants has signed a deal with biometric security company Clear to provide a pre-screening process for fans.
