From my team my biggest overperformers have definitely been Morse at 1.5 (on fire the last few weeks) and Stauffer at 0.5 (my current ace of the rotation because of Anderson's problems lately. Other than that Francis at 2m, Chipper at 3.5m, Hafner at 5m and newly acquired Abreu at 5.5m have been very productive for their salaries. Their counterparts would be Harang at 5.5m, Vazquez at 6.5m and newly acquired Roberts at 9.5m.
