“For the 2013 baseball season, Major League Baseball is more than tripling the number of stadiums that will accept mobile tickets via Apple’s Passbook app,” Erica Ogg reports for GigaOM. “This year there will be 13 stadiums that will enable paperless ticketing via Passbook, MLB announced at a fan event in New York City Tuesday night. That’s up from four last season.”

Ogg reports, “The teams that will start accepting Passbook tickets for the first time are the Minnesota Twins, Baltimore Orioles, Milwaukee Brewers, Oakland A’s, Pittsburgh Pirates, Detroit Tigers and Chicago Cubs. The New York Mets, San Francisco Giants and Kansas City Royals, which began accepting Passbook last September, will again offer the service this season. MLB says there are three more teams that will enable iOS tickets this season, but that are not yet ready to make an official announcement.”

Ogg reports, “Last week, MLB debuted the 2013 edition of its At Bat app… which included more live, archive and embedded video content, and a new deal to include free game audio access.”
