The season of MLB free agency is underway, and all 30 teams are beginning to make over their roster. Some have already made moves such as declining options, while others have done their best to keep their roster intact, namely CC Sabathia re-signing with the Yankees.

Despite this, there are always signings that blow up in teams' faces, like Adam Dunn and his embarrassing batting average with the White Sox. Here are 20 free agents who could end up being the next Dunn.
