8. Prospects may be kept on an MiLB roster until the following MLB conditions are met:
Hitters: 500 career PA
Pitchers: 26 career X [where X = GS + 0.5(relief appearances)]
9. Once a prospect has crossed one of the thresholds in rule 8 above, he/she must be promoted to the MLB roster no later than the next February Prospect Cutdown or the next Annual MiLB Draft Prospect Cutdown, whichever comes first. If a player crosses the playing time threshold but is not actively cut or promoted at the relevant cutdown, then they are effectively a free agent and they can be selected in the annual waiver draft or added as a free agent in Yahoo (The Jake Lamb rule).
