Karsten Whitson is a teenage pitching prospect who might have had the highest ceiling of any of the 2010 draft class participants. Unlike most pitching prospects, who lack for a serious gap or two in their toolset, Whitson already showed a near-ideal mix of stuff, polish, pitchability and projection. His fastball was an MLB-ready 92-94 version with sink, and his slider, a hard 84mph version, showed real plus break. His third pitch was a straight change that, while still below MLB caliber, was already leaps and bounds better than what one usually sees in such a young player. The Padres were unable to sign Whitson, however, so his mailing address will be at the University of Florida for the next two or three years.
