What about David Phelps from the Marlins? He's moved to a full-time relief pitcher this year and his stuff seems to be playing up quite a bit. Striking out 10.25 per 9, his FB average is up around 3 MPH and his cutter average a little over 2 MPH (he throws those pitches about 91% of the time). He's also topped out an nearly 97 MPH on his FB and has hit 95 on his cutter. He's olderish, 29, and is in arbitration. I can't imagine the Marlins would be too stuck on keeping him, seems like he could be had for maybe only 1 player like a McKinney and maybe a wild card pick like a Black or Rivero, etc.
