Has anyone actually ever gone from A-ball to the majors, let alone actually had success in doing so? I know guys do it from AA but I can't remember anyone going from single A. edit: I'm sure there's plenty of guys (mostly pitchers) out of college that have done so. I think Mike Leake might've gone straight to the majors the following year after being drafted. I'm not sure if he made any stops along the way. But I'm wondering about guys that weren't "super-prospects" in terms of being ready out of college. In other words, guys who started in rookie ball, then A, then A+, then a jump to the majors.
