Well, in general terms you may have a point. I guess I'm looking at it specifically from the point of view of the Red Sox having Yoshida. The only way this guy can have any possible value is as a full time DH. If he can't hit lefties and has to be platooned, he's a severe impediment to in-game roster flexibility. He could theoretically grab a glove and play OF, but it seems like the team wants no part of that. So if he can't hit lefties, he's simply a liability.
