Obvious caveat before I begin: I'm just a guy who watches baseball, so take what I say with a grain of salt. Rowell played a mean shortstop at the high school level - I was very impressed with his defensive game. Having said that, I have definite questions at his chances of sticking on the left side of the infield long-term.

He played a ridiculously deep shortstop at Bishop Eustace, positioning him self so far back that he would stand on the cutoff where infield dirt meets outfield grass at times. I have to figure that he played so deep in order to hide his lack of range and lateral mobility...though on the plus side, he could only get away with playing so deep because of his plus arm strength. Obviously these reasons are why the Orioles see him as their third baseman of the future

Rowell does not lack in athletic ability - the guy moves well enough for a big man and has at least average footwork. Unfortunately, he had a very bad rap around town about not being receptive to coaching, so the conversion to third will be extra difficult if he continues to resist advice.

If I had to guess right this second what position he'd play most in his big league career, I'd guess RF. I think he'll be good enough at third base to stay there in his younger years, but will have to move to the outfield sooner rather than later once he reaches the bigs. To me it comes down to this: either his lack of lateral quickness could be a problem at third OR he could have some crazy natural reactionary instincts that help him stick at the new spot - third base is one of the tougher positions to predict in my mind as it requires such instinctual movements. His arm is plenty strong for the spot, it's a matter of range more so than anything else.

Sorry if I kept going in circles, I suppose it just shows that where Rowell will wind up is still very much open to debate.

the high school ranks are stacked this year.  power arms from both the left and the right side and good position prospects all over the diamond.  the college position players may be a little weak, but there are some good ones.  matt wieters would be one of the best in any year.  mangini and frazier could be pretty good players.  there may not be a whole lot of college righties that are first rounders, brackman and arrieta are the only 2 i think i would take in the first round at this point, but there are a bunch of guys that are sandwich round/2nd round types.  guys like bryan augenstein, wes roemer, james simmons, sean morgan, brad meyers, and of course the closers josh fields, casey weathers, and eddie kunz.  like you said it is a very good class for college lefties.  david price, ross detwiler, daniel moskos, joe savery, sean doolittle, and nick schmidt are all legit first rounders and so is cole st. clair if he can somehow make it back this year.  brett cecil is another lefty reliever that could sneak in to the tail end of the first rounder b/c he has great stuff.
