Al; One of Huntsvilles regulars can answer this better than I can... but I'll add my own personal observation from last year. When I saw Nelson in Huntsville, I thought his arm was pretty good- it wasn't a cannon or anything, but it seemed solid to me. It was a lot more accurate than I thought it would be, too, considering his relative lack of experience out there. Overall, he looked to be in GREAT shape, and he moved around out there very well. He's not the lumbering first baseman I remember from Beloit or his first go around in Huntsville in 2003. I'd say his arm is at least strong enough that he's got a shot at playing there, even if it would make him one of the weaker throwing ML RFers.
