Zach Stewart

Like Andrew Cashner, Stewart is a former junior college starter who has thrived after transferring to a Big 12 school and moving to the bullpen. His best pitch is a 92-96 mph fastball with filthy sink. Early in the season, he showed a sharp slider that some scouts graded as a plus-plus offering, though it has become more sweepy as the draft approached. Stewart also shows the makings of an average changeup in bullpen workouts, leading some clubs to think he could move back to the rotation in pro ball. But as a starter at North Central Texas CC in 2007, he pitched at 88-90 with his sinker, a lesser slider and diminished control. Texas Tech moved Stewart into the rotation late in the year, and he gave up 16 hits over nine innings in his first two starts. His 6-foot-1, 175-pound build and inconsistent command also seem to make him more suited for relief work. A possible first-rounder at midseason, Stewart is more of a sandwich- to second-rounder now.
