On the field there has been no lack of controversy, from the new replay rules, to injuries, to maturity problems, to illegal substances. The MLB installed new rules to determine out/safe calls and the security of a catch in the field. This seems pretty straightforward, but came under critique when several calls where made when a player dropped the ball when moving it from his gloved to his off hand. The MLB later made a statement to make a more uniform ruling, and concluded that once a player has the ball in his glove it is a completed catch.

Everyone so often we see the public rise up in arms about how a certain athlete has wronged them, or an athlete will become frustrated with how he is being treated by the fans.
