The 2012 season will give a number of MLB players the chance to prove themselves. Some will be trying to prove that 2011 was a down year. Others will be trying to prove that the great numbers they put up in 2011 were not a fluke. Players returning from injuries will be trying to prove that they can play at the level they did before they were hurts.
There will be a new beginning for all of these players, and they need to make the most of the opportunities that they are given. Some players on this list will play well enough to cast off an doubts about them while others may end up losing their jobs if they struggle.
