Really, Yost has never used him for more than 1 to 3 lefties. Um, yeah, do you follow Brewer games very closely? Do a little digging and see how often Shouse has only faced 1 to 3 lefties, and compare that to how often Yost uses him for several (more than three) batters or more than 1 inning in a game. I think that you will be surprised at what you find.
