I put my new draftees and IFAs in either high or low A, depending on their age/current ratings/ coaches' abilities. At the end of the season, I promote them one level, since that seems to I've them am extra ratings update about 50% of the time. So a typical prospect starts at A ball, plays at AA in year 2, starts at AAA in year 3. If he's a truly good prospect, he's good enough for the majors in his fourth year, or even after 20 games in his third year. If not, I'll leave him in AAA for a couple years.
