Don't put 100% faith in the system right now either. Video replay consistently shows the umpire made the right call and that the PitchF/X data is way off by considerably more than a "1/2" inch. Note a few of the pitches right down the middle of the strike zone have been marked as a called ball pitch. Likely, some of the balls outside the zone have been marked as a called strike pitch. Joel Zamaya was reportedly clocked at 103mph by Pitch FX data which was later shown to be incorrect. There are bugs creeping into the system that conflict with video replay and the standard radar gun.
1) Note Werth and Polanco's individual strike zones.
2) Note path of ball over plate in Sonnanstein to Posada
3) Note all those inside/outside strikes.
I saved a copy of some of those "confusing" comments I made and deleted in the gray strike zone thread which have now been validated by MLB Pitch FX data.
