6. Oakland Athletics, J.B. Bukauskas, RHP, North Carolina

Though he's only 6-feet and 195 pounds, Bukauskas is viewed as having the best pure stuff among college pitchers, with a 94-97 mph fastball and a mid-80s slider that both grade out as plus or plus-plus, depending upon whom you ask. In addition, his changeup projects to be at least average. There's concern about the lack of plane on his fastball, however, as well as a high-effort delivery that doesn't make use of his lower body, so there's a chance he becomes a late-inning reliever.
