I mentioned similar arguments in another thread, but another thing to note is that he's faced a pile of very tough lefties. In 70ish AB, he's faced Sabathia 2x, Cliff Lee, Pettite, Holland, Price, Chen, Moore. The guy is 32 years old, healthy, and he's played in pitcher's parks most of his career. At some point his hits will land, and he'll be back to crushing lefties.
