I think I disagree with the above regarding a min on control rating. However, I think my disagreement is near moot because I don't think I have ever seen a guy with 20 control, but 90+ in at least three other of the following ratings -- L split, R split, p1, p2, p3, p4. I am willing to bet that a guy with 20 control, but 90/90 in splits and then a 90\70\70\60 in pitches, would still be effective. His BAA would be around .205, his obp would be .335, but because his slugging would be so low, I think he would still pitch with an OPSA of under .700. If you throw in an elite GB rate of 88+, and I am nearly certain a guy like this is effective during the season. I doubt I would give him many playoff innings, but in the regular season, it would be nice to try. My main worry is that his pitch counts spiral upwards.
