Yankees fans can expect tighter security than usual at Tuesday's game against the Astros.
Stadium officials say metal detectors will be set up throughout the park.
Major League Baseball has been working with the Department of Homeland Security to standardize security measures at all 30 stadiums.
The uniform measures are set to take effect at the start of the 2015 season.
The Yankees say they are installing the detectors early in order to get both fans and staff used to the new procedures.
