The list of apps includes MLB.com At Bat 13, At The Ballpark, Beat The Streak Presented by Dunkin' Donuts, and MiLB.com. In addition, At Bat is making its debut on the new BlackBerry Z10 smartphone with features including MLB.TV live video streaming.

MLB.com At the Ballpark
The ultimate mobile companion when visiting any of the 30 MLB parks. MLBAM has built the app to be customizable for each ballpark from a foundation of interactive features, including mobile check-in, social media integration, offers, rewards and exclusive content.

Features include rearchitected My Journal section; manually input all ballpark visits, dating back to 2005; upload and share personal photos from all ballpark visits, dating back to '05; view team statistics and watch video highlights from games attended; ballpark and player entrance music; social media clubhouse, including social rewards for select clubs; updated tickets section, featuring special offers by club; seat and experience upgrade functionality (select ballparks only); Passbook integration for digital ticket delivery and storage (select clubs only); and a redesigned user interface.

MLB.com Beat the Streak Presented by Dunkin' Donuts
Keep an eye out for this update anytime now. Maybe season No. 13 will be the lucky one. Entering its teenage years without a grandprize winner, this app is free to play and gives fans the opportunity to achieve fantasy baseball immortality by surpassing the legendary consecutive games hitting streak record of 56 and claiming a $5.6 million grand-prize in the process. Tens of millions of streaks started. No grand-prize winner. Yet ...

You'll have the ability to get pick results by push notification as well as improved reminder notifications, and you can easily follow live-game scoring for your picks in MLB.com At Bat 13. Here's a new game rule, too: A streak won't end if a user forgets to make a pick.

MiLB.com app
MLBAM also produces the popular MiLB.com official app for Minor League Baseball fans and for Major League fans who want to track their organization's pipelines. This app returns for 2013 with new features and improvements. Follow every pitch of every game from Minor League Baseball's top two levels with Gameday. Also, MiLB delivers complete stats, schedules, standings and the latest news for every Triple-A and Double-A club.
