Steady contact rate with declining OSwing% seemed like a bad thing to me at first take (would seem to suggest he was missing more in the zone), but ZCon% is pretty stable as well (73.9%, 75.4%, 75.8% for June, July & August, respectively). It would appear he's just missing a larger percent of those pitches outside the zone that he's offering at (OCon%: 17.9%, 11.1%, 7.1%). I would think that that's a good thing (to the extent that swinging and missing can be a good thing); it should translate to less poorly contacted balls.
