By now if you're a baseball fan, you've become accustomed to having your bags checked as you enter the stadium. Get set for a higher level of scrutiny.
Major League Baseball has mandated metal detectors at all 30 ballparks by 2015, The Associated Press reported.
"This procedure, which results from MLB's continuing work with the Department of Homeland Security to standardize security practices across the game, will be in addition to bag checks that are now uniform throughout MLB," baseball spokesman Michael Teevan told the AP.
The Mariners said Tuesday that metal detectors are in place for their opener April 8 against the Angels.
"We conducted testing of these measures at the All-Star game and at both World Series venues last year, and we were pleased that it was effective and received without issue from fans," Teevan told the AP.
