It now appears "likely" that baseball will introduce playoff expansion for the 2012 season, according to sources. According to the terms of baseball's new labor deal, Major League Baseball and the players' association are required to reach an agreement before Thursday or postpone playoff expansion until 2013. Multiple sources have declined to reveal any details of the talks, but the sides have made enough progress that one source said, "The feeling is now that it's likely that something is going to get done."
