"Prospect" just in that he's only ever been a minor leaguer outside of 4 MLB innings, but RJ Alaniz has put up some very nice numbers in a beleaguered Louisville bullpen. 25 strikeouts and a 1.50 ERA in 24 innings. He is on the 40 man, I'd give him the call before I turned to Herget again (or Mella or Stephens for that matter).
