PHILADELPHIA -- Beginning next season, every fan will be screened for security purposes before entry into every Major League Baseball ballpark.

Metal detectors will be introduced as part of a pilot program beginning July 21 at Citizens Bank Park.

The Phillies said in a news release on Monday that the increased security measures are the result of MLB's continued work with the Department of Homeland Security aimed at standardizing security practices across the game. Fans entering Citizens Bank Park through the Right Field Gate will be required to pass through a metal detector before tickets are scanned.

"The safety of our guests is our top priority," Phillies director of operations and security Sal DeAngelis said. "We fully support MLB's efforts to implement these enhanced security measures, and look forward to working with them during this pilot program. Next year, we expect that metal detectors will be at all entrance gates."

Cell phones, cameras and other large metal items will need to be removed prior to passing through the metal detectors.

Unlike Transportation Security Administration screening at airports, fans will not be required to remove shoes or belts. Fans who cannot pass through a metal detector will be checked with a hand-held device.

The new procedures are in addition to bag checks, which are already in place. Bags still must be no larger than 16-by-16-by-8 inches.
