Over Hosmer? Get out a town.
If Hosmer hits at Fenway and the AL East parks as he has in his career, then nobody is moving him out of the line-up. And if JD is not back next year, the DH spot will need filling.
I don't know what change he made, but if he can keep his numbers vs. lefties up and return his numbers vs. righties back to where they have usually been, then I'll have no complaints.
