17. A.J. Burnett

Year: 2008
Contract: $82.5 million/Five years
Team: New York Yankees
Never the type to miss out on scooping up big free agents, the Yankees targeted A.J. Burnett who had gone 18-10 and led the AL with 231 strikeouts while in Toronto the previous season. With the Yankees, Burnett has gone 32-25 and recorded a 4.81 regular season and 5.67 postseason ERA. Oh yeah, then there's that time in 2010 when he punched a door after a loss injuring his hand in the process. Classy.
