The 2012 MLB season has just begun, but even this early in the year teams are going to start thinking about how they can improve for next year. Of course, they're going to want to win now, but there's no harm in thinking about areas of improvement.
This leads to the 25 best MLB free agents for 2013. Since the offseason, the rankings have changed thanks to a big contract extension given to Matt Cain and Ian Kinsler, knocking them off the market.
Not too long ago, I wrote an article on the top 20, so I will note their rank in the previous list to show any trends.
