How well would he have to play at shortstop to really muddy the waters after that level of pitching performance? Serious question here, I mean I'd love nothing more than to see the guy dominate the league at SS, but we're talking abou a 19 year old putting up solid numbers at Class A Advanced. That's pretty awesome stuff, I'm not sure if anything he does in Lowell is going to compare. he'd basically have to hit 10 HR's in a month and a half or something obscene like that.
that said, I definitely want him playing SS if his body can handling it. If nothing else, having it on your resume in the minors opens up possibilities in the majors if we need to make some odd substitutions in a game, or something. Having a pitcher who can play regular infield as an emergency option just increases his usefulness, even if it doesn't happen in a given year.
Also, if the guy can keep swinging the bat a little here and there against live pitching, that'll be useful during interleague play.
