In his first big league at-bat, Cubs pinch hitter Adam Greenberg is struck in the back of the head by the first pitch he sees from Marlin hurler Valerio de los Santos. The 24-year old Guilford, Connecticut native is forced to leave the game, but will be okay after the dizziness and headaches caused by a mild concussion wear off. The at-bat will remain his only taste of major league action until the Miami Marlins give him a chance to have the “at-bat he never completed” on the last day of the 2012 season.
