Haven't gotten to see him in AA. Hope you're right on the defense. He didn't look comfortable at all at Potomac.
He still isn't a "good" 1B, but he isn't on the same level he was at with Potomac for sure. If I had to project him based on his performance this year and his potential, I would say he has the potential to be an above average 1B. Agree on the bat, though, he needs to make some strides in the next year.
