well....i'm hoping the twins minor league instructors have been working with him, because...that's kinda what they're paid to do. most of it is just the basic evolution of a prospect, imo. sano's raw tools are similar to previous years, he's just able to control the strike zone better, which is a key adjustment you hope every marquee prospect is able to make. with that said, i dunno which set of news is better - his continual evolution as a hitter or his now apparent ability to remain at third base. his prospect value increases dramatically at third, imo.
