At this point, I think there is still room to be just a little more optimistic than a net 1 career WAR guy in May- but this year in AAA he has to step it up, no doubt. You mentioned his ERA ranking, but that stat is a little skewed by May being victimized by a big jump in BABIP to .330 and a huge spike in stolen bases given up by Rock Cats' catchers. And despite that 45th ranking in ERA, his FIP was actually a very good-to near-dominant 9th in the Eastern League and 3/4 of a run below his ERA at 3.79, confirmed by an also-excellent SIERA of 3.67, indicating that there might be an improved year coming up. Also of note, besides his upticks in improvement in K/9 and BB/9, May was a definitely dominant 3rd overall in the Eastern League in K% at 24.1%, which is excellent. Finally, year-over-year, with the above-noted improvements and no regressions of note, May also significantly cut his LD% from 21.4% in 2012 to 12.9%. I think there's back-end starter stuff somewhere inside of May, I think there's a case to made that it's all a matter of his mental approach, hopefully the Twins coaching staff can help bring it out to the point that he becomes a legitimate depth option by the end of 2014. In conclusion, I don't think it's unreasonable to say he's no more than 50-50 at ever being a major league starter.
