I think that his BA will be closer to .250 than .300 at the rate he is going. His K/BB is 9/1 and unless he improves that department, I can't imagine he can maintain the AVG.
Also, he is not hitting lefties. He's sitting also vs. lefties. I think he will definitely hit 30 HR but expect some bumps on the road.
