ID=7709993CLEVELAND -- The Indians have announced new security measures at Progressive Field as part of a Major League Baseball initiative to standardize security practices across the league.

Walk-through metal detectors will gradually be added at all gates.

The first installment of metal detectors will be at Gate D, behind home plate, beginning with this homestand.

Any fan coming through this gate must be screened. Fans can also choose to be screened by hand-held wands instead.

Other metal detectors will be added at gates A and C later this summer. The new security measures will be finished by opening day 2015.

"This will be a minimal, unobtrusive change for our fans, whose safety is our No. 1 priority at the ballpark," said Jim Folk, the Indians' vice president of ballpark operations. "Fan convenience is very important to us, and we're making every effort to ensure these important safety measures, as mandated by Major League Baseball, will have a minimal impact on fans' speedy entry into the ballpark."

MLB has been working with the Department of Homeland Security and the individual clubs on the initiative. Quicken Loans Arena and FirstEnergy Stadium already have similar security measures in place.
