4. Ryan Dempster –

Jon Daniels was trying to sure up the rotation for his Texas Rangers when he decided that they just needed Chicago Cubs pitcher Ryan Dempster to help them compete in 2012. The Texas Rangers traded third baseman Christian Villanueva and right-handed pitcher Kyle Hendricks to the Cubbies for Dempster, who had an ERA of 2.25 with the Cubs, but an ERA of 5.09 with the Texas Rangers. Dempster and the American League did not agree in 2012, and he did nothing to help the Texas Rangers chances of getting back to the post season for a third straight season.
