I didn't say that I have Pitch f/x from the minors. I don't need it--I'm referring to the 275 pitches he threw in MLB. "Three games" sounds small, but 275 pitches is a reasonable sample, particularly if the performance is suspect: and when an ERA goes down from both AA and AAA in MLB, especially from a pitcher who's not necessarily forecast to excel in MLB by scouts, many might consider the performance suspect.
Look at the actual results from last season. Take his first game, the one that caught my attention. There were four strikes, all in the bottom inch of the zone, called balls: pitches 1, 30, 32, and 54. There were 13 balls called strikes: pitches 10, 16, 21, 27, 45, 65, 67, 71, 77, 85, 92, 95, and 96. Even if one expands the strike zone from the regulation zone by four inches to account for umpires giving pitchers "the black," there were still nine outside pitches that were called strikes, pitches that missed by as much as about half a foot. Kerwin Danley didn't extend that same courtesy to the Rays' pitchers...it was a clear case of favoring Kennedy.
