Opinions on pitching prospects are like snowflakes; each one is unique and possibly moments away from evaporating. Even once a young arm gets a considerable number of professional innings under their belt, it is conceivable that everything comes crumbling down if/when they make the jump to the major leagues.
That said, the Orioles find themselves in a somewhat envious position when it comes to high-end young pitchers. Currently with Double-A Bowie, 21-year-old righty Grayson Rodriguez has become recognized by two outlets (MLB Pipeline and Baseball America) as the top pitching prospect in all of minor league baseball.
