White Sox' Ozzie Guillen To Promote New Social Prediction Contest GameSlam

White Sox manager Ozzie Guillen has signed on as a celebrity "Slambassador" to GameSlam, a startup social sports prediction game. Guillen will occasionally participate in the game, offer strategy tips and promote Game Time Live Sports Services LLC, the Illinois-based makers of GameSlam. The game itself operates somewhat similarly to Pre Play Sports and other prediction contests that function as sort of a second-screen companion to live games, with users accumulating points based on their ability to guess the outcomes of specific upcoming plays. GameSlam, however, is seeking to differentiate itself with a more console-like, graphical game experience, a deal with Stats LLC for the real-time data feeds, and a variety of custom leagues, challenges and social media tools.
