Now I'm sure they probably don't have the time to go back and verify each pitch (maybe if they get their data from BIS they do), but this is why I could see their classifying being the way it is.

You see this with cutters/sliders, splits/changes, and occasionally curveballs/sliders. Is it just noise in the data, or is there some legitimate reason for calling one 81 mph glove side-moving pitch a cutter and calling another 81 mph glove side-moving pitch a slider?

Even if his FIP regresses a bit this year the Oakland defense hasn't disappeared, so his ERA will probably still come in a little but under his FIP. A 3.69 ERA is great in my opinion.
