Ofelky Peralta

At 19 years old, Peralta more than held his own at Low-A Delmarva in his first shot at full-season ball. There, opposing batters hit just .230 against the projectable righty. The 6-foot-5 hurler throws hard, but his command remains erratic, and his secondary pitches are still works in progress. Nevertheless, the Orioles expect the Dominican product to put on some muscle and fill out, and the strikeout potential is certainly evident (22.4 percent strikeout rate). There's an argument to be made that Peralta has the most realistic upside of any starting pitching prospect in the Baltimore system right now, although that is not saying much. He is still rather raw, but will start the season at High-A Frederick where he will work on hitting his spots and honing his offspeed offerings.
