A Few AFL PITCHf/x Leaders
I like the Arizona Fall League. I've been tracking and classifying a lot pitches, thanks to the PITCHf/x installations in Peoria and Surprise. Nearly 10,000 pitches through Saturday's Rising Stars Gam...
NLDS Game 1 - Power Yields to Finesse
Cliff Lee's post-season debut turned into a complete game gem. Losing a shutout in the 9th was not completely Lee's fault, but, as it goes with baseball, your success as a pitcher isn't your own, eith...
Masters of Deception
J.P. Howell has been the most deceptive pitcher in 2009, Daniel Cabrera the least. I'm defining deception in a simplistic manner: called strikes per takes. But, it's calculated by count, relative to t...
Graph of the Day: Expected Run Values (beta)

Slicing The Pitch F/X Leader Boards
Back to some RV100 (average run value compared to average of 100 pitches) leaders, this time by lateral slice. "Fat" pitches are the middle ten inches of the plate, "Out" and "In" are the next 7 inch...
Not Your Typical Pitching Stats
You know I'm mildy obsessed with PITCHf/x. I often present this metric or that metric, this pitcher, that pitch. Today I'm going with some of those familiar metrics, but by pitcher (not pi...
