Why would you want Guzzy over Morgan at the top and Gonzalez over Kennedy?
If you look at his OBP the last 3 years vs. LHP: .380, .323, .410 he is fine in that spot. I would pinch hit him the first time a RHP comes up. But, Riggleman would never do that.
Gonzalez vs. LHP is infinitely better than Kennedy
Morgan is a disaster vs. LHP
