Professional baseball players have something to prove every day, but each year a certain group of individuals arrive at a critical junction of their respective careers.
The following players all enter 2014 under the microscope. At one point, perhaps as recently as 2013, all were stars. As we often are reminded, the past matters little when it comes to public perception.
In order to change the narrative or stave off an avalanche of criticism, all of the players on this list must play well in 2014. For some, it means rebounding from injury. For others, it's justifying a new long-term contract. For one in particular, it's reshaping an image that may be stained forever.
When spring training arrives, expect to read and hear stories about every individual on this list. Many will be counted out, but by the end of 2014, a few could re-emerge into the spotlight once again.
Without further ado, the players with the most to prove during the 2014 season.
