The Chicago Cubs have announced a couple of significant roster decisions on Saturday morning. After some serious struggles over the last couple of weeks, the Cubs have designated veteran right-hander Genesis Cabrera for assignment. Chicago acquired Cabrera at the end of May after he was waived by the New York Mets, but things simply have not worked out for him with his new team. In nine Cubs appearances, Cabrera posted an ERA of 8.68 and just could not keep runs off the board.
