Pick one pitcher for a trade...

In my 14 team 5x5 keeper league, I more or less put a For Sale sign on my team. One team was interested in getting Brandon Phillips but I am also thinking of throwing in a pitcher to upgrade a high end player as a keeper, I'm just not sure which pitcher to initially offer. Here's what I am thinking to offer: My players: Brandon Phillips Pick one of Liriano, Haren, or Greinke For his players: Dan Uggla Ryan Braun I'd think Liriano is the best bet since he is my best pitcher over Haren & Greinke but Greinke has the upside to rebound and do well but without the wins, obviously. I have plenty of very young players to keep for next year but I need that sure fire slugger to solidify my offense, which was my problem this year. Keeper rules are the cost of each of the 5 players that can be kept is based on the 2011 Yahoo Overall rank (1-14 = 1 rd. price; 15-28 = 2 rd. price, etc.) Here's my roster: C Brian McCann (Atl - C) C Buster Posey (SF - C,1B) 1B Mark Reynolds (Ari - 1B,3B) 2B Brandon Phillips (Cin - 2B) 3B Pedro Alvarez (Pit - 3B) SS Elvis Andrus (Tex - SS) CI Pablo Sandoval (SF - 1B,3B) MI Erick Aybar (LAA - SS) OF Jay Bruce (Cin - OF) OF Ryan Ludwick (StL - OF) OF Andrés Torres (SF - OF) OF Daniel Nava (Bos - OF) OF Matt LaPorta (Cle - 1B,OF) Util Adam Lind (Tor - OF) P Ryan Franklin (StL - P) P Tyler Clippard (Was - P) P Fausto Carmona (Cle - P) P Dan Haren (Ari - P) P Zack Greinke (KC - P) P Clayton Richard (SD - P) P Francisco Liriano (Min - P) BN Neil Walker (Pit - 2B,3B) DL Kyle Blanks (SD - OF) DL BN Jonathon Niese (NYM - P) BN Madison Bumgarner (SF - P) BN Jeremy Hellickson (TB - P) NA BN Erik Bedard (Sea - P) DL DL Brett Anderson (Oak - P) DL Thanks everyone.
