That's been my concern with him all along. And I don't think his bat is ready yet. OTOH, he's not a high-ceiling guy - he has a chance to carve out a career in the majors for a few years, maybe even sneak in an all-star invitation one year if things break just so. I'm thinking an outfield Nick Punto, in which case his usefulness could even go on for years. So there's no reason to play service-time games with him, nor endlessly fine-tune his approach to eliminate all exploitable flaws so as to get the most out of his boundless talent. As soon as his bat is marginally ready, bring him up, and start reaping whatever defensive value he brings. This is what other teams manage to do on a regular basis, supplying the major league team with 2- and 3-tool players who fit a present need, even if it's only for a few short seasons. It's a cold business, sometimes, but conversely Granite has a golden opportunity if time and fortune mean he is able to grab it.
