Spec. preached mightily on the need to have a good eye in the minors in order to make it in the majors. If he carried this .30 eye into the majors I would definitely be scared off, and DiPo would probably be as well. So what does having a good minor league eye, with decent power, say to us when it translates (so far) into a .28 or so eye in the majors. Do we, for a 27 year old player, expect the further decline we saw in his injury plagued season? That would certainly be the safest bet.
I suspect that maybe DiPoto sees more than a mere glimmer of hope in the entire body of work - a good eye in Martin's past, and thus is willing to take the gamble that it can improve under the tutelage of an Edgar and an organization that stresses tough at bats. There is something here to work with. If there wasn't, he wouldn't.
But the glimmer+ has to come with good glove and baserunning skills.
