This is a post of maximum information and minimum interpretation, simply because I love PITCHf/x, I love Felix, and I love putting two things I love together into one thing I love even more. Like a fighter jet made out of gummy bears.
Note: pfx = movement in x (inches), pfz = movement in z (inches), StL% = percent of strikes looking, StS% = percent of strikes swinging, StF% = percent of strikes foul, StI% = percent of strikes in play.
The real fun thing to do with this, I think, is examine Felix's tendencies. For example, against righties, it looks like he uses the fastball to try and get quick outs, whereas the slider is his strikeout pitch low and away. Against lefties, he hammers the outer half with fastballs while going down and in with the slider and down and away with the changeup. The curveball's in there against both righties and lefties to screw up their timing (look at those absurd StL% rates).
Too much fun. Happy Felix Day.
