SSS, but Miley's .308 BABIP is in line with his .303 career average and he's yielding just .57 HR/9, so it would seem that the problem is less grooving too many pitches that are getting hammered than it is throwing up a walk rate over 6/9 and suffering a sub 50% strand rate. Even his low K rate isn't that far out of line with his career prior to 2014. Small consolation, but his FIP is almost 4 turns below his ERA.
According to data pulled from Baseball Savant, Miley saw a large uptick last year in his called strike rate on pitches thrown out of the zone, which likely played a role in boosting his K rate to a career high. Despite those extra strikes, he still worked outside the zone so much that his walk rate also jumped to a career high (excepting his 7 starts in 2011). Some of what's happening is probably just reversion and he's not going to have the same success staying outside the zone, though that's unlikely to fully explain a 6.32/9 walk rate. The PitchFX chart posted above also doesn't seem to be painting a picture of someone who just isn't getting borderline calls.
If he brings that walk rate down the problem may work itself out leaving us with our mid/back end of the rotation starter. If it doesn't, hard to see anyone- including Miley- finding fault with a phantom DL stint and some rehab starts.
