He just turned 20 last week and is a big, left-handed 1b. He is still filling out, but the k/bb ratio is pretty good (35/64) for a kid his age at his level and I think he'll develop more power than his current once-every-fifty-at-bats would indicate.
I'm quite hopeful. Not for the near future, of course, he's nowhere near ready. But around the time Delgado's contract is done, we may have another home-grown star on our hands.
