"Without LEV being brought into the mix, Saito's season wouldn't look as amazing as it really is."
Nobody uses this as a measure to determine how good a closer is. I can make up a stat tonight which points Papelbon being the best closer. All fickle stats aside, Putz has been the best. Besides you people in LA, I dont think many people give a s*** about Saito. I would also give the edge to any American League closer over a National League closer since they deal with tougher lineups, and a National league closer has a 33% chance of facing someone pinch hitting in the pitchers spot every time he comes in to a game.
Only legit closers in the NL are Cordero, Wagner and Hoffman.
