Pitchf/x Page Fixes
Just some quick notes on the 2010 pitchf/x data:
– There appears to be some new pitch type categorizations that were breaking some pitchf/x pages. There is EP (Eephus Pitch), SC (Screwball), KC (Knuckle Curve) and FO (Forkball).
– SC and FO I have temporarily lumped into FT (Two-Seam Fastball). I’ve been explained that screwballs (and possibly forkballs) are not really two seam fastballs, but there have been a total of 19 screwballs thrown this year, 18 of them by Daniel Ray Herrera and then the other one was thrown by Dallas Braden. There have been 12 Forkballs thrown, 8 by Livan Hernandez and 4 by Kenshin Kawakami. Overall, these two pitches didn’t seem to warrant their own category, but I can be convinced otherwise.
– Eephus pitches (EP) I have lumped into the UN (Unknown) category. Vicente Padilla has thrown all 16 of them.

David, I’m curious why you chose to lump SC and FO with FT. In terms of velocity, break and usage I would think they’d be more similar to CB or CU. Or is that assumption wrong?
A screwball breaks the opposite way from a curve or cutter.
