Just in case somebody comes back with the "that's not bias according to Wooldridge", PitchF/X data is biased in that there are adjustments in the data to get everything to fit into the "strike zone" box.  Also, that data is also only two dimensional so any breaking pitch that crosses a corner isn't going to get picked up by PitchF/X like it does by a live ump looking over the plate.
