A good April is a good April. May didn't start well, but that's another story.
Here are some PITCHf/x goodies. I'll post various items over the next few days.
Release points standardized to 55ft. Wrigley Field only, since the park-to-park differences are enough to make me cringe. I'll learn more about corrections to the data at the PITCHf/x Summit next weekend.
PFX is inches of spin movement from 40 ft to 1.417 ft. (home plate), other values are feet for release points and plate location. Degrees and Spin rate are also shown in some cases. Numbers subject to change if I find errors in my system. The mph going down the hundredths is questionable, the numbers aren't that precise.
