**Stats Glossary:**

Rk: rank the pitch has among all qualified pitches in the indicated category;
**PRk**: rank the pitch has among only qualified pitches of the same type (e.g. curveball) in the indicated category;
**T**: arm the ball is thrown with;
**P or pitch**: type of pitch thrown;
**%**: percent of the time that pitch is thrown;
**count**: number of data points for that pitch;
**R/100**: just ignore because I originally screwed up the formula, but it is corrected with a detailed explanation here and in the .csv files;
**BABIP**: batting average when that pitch type is hit into play including home runs;
**SLGBIP**: slugging percentage on balls hit into play;
**S%**: percent of pitches resulting in a strike (anything but a ball) for said pitch;
**%IZ**: percentage of pitch thrown in the strike zone.
**Con or Con%**: contact rate ((fouls + hit into play balls)/(pitches swung at));
**Sw%**: % swung at;
**SW%**: % of pitches that are result in a swinging strike; **
B%**: % that are balls;
**CS%**: called strike %;
**F%**: % of pitches fouled off;
**InP%**: % hit into play;
**GO**: percent of times groundouts result when that pitch is hit into play; ect., ect.
for fly outs (**FO**), pop outs (**PO**), line outs (**LO**), singles (**1B**),
doubles (**2B**), triples (**3B**), home runs (**HR**).
**Fish**: Dan Fox stat, how often the batter swings at the pitch when it's out of the strike zone;
**BadBall/ConOZ**: another Dan Fox stat, percentage of time swings at a ball out of the strike zone make contact, so the lower the better for the pitcher;
**K/100**: number of strikeouts resulting from indicated pitch per 100 pitches thrown by pitcher, adding up all K/100 values for a pitcher would give his K/100 regardless of pitch selection;
**P/E**: average for all pitches;
**S/E**: command indicator, the average distance from the closest strike zone edge for strikes and
**B/E**: average distance from the closest strike zone edge for balls;
**S/C** being from the closest corner;
**Vs.R**: preceding stat against only right-handed batters;
**Vs.L**: preceding stat or stat preceding Vs.R against left-handed batters;
**ucR/100**: R/100 uncorrected for the frequency the pitch is thrown, so the metric theorizes a world where only the indicated pitch is thrown, which of course would take away its effectiveness
**ucK/100**: uncorrected like ucR/100 for strikeouts

**Pitch f/x:**
**V0**: average speed in mph when pitch is 55 feet from home plate;
**Vf**: speed in mph just before the ball crosses the plate (1.417 feet from plate);
**time**: time it takes the ball to travel 55 feet from home plate to 1.417 feet from the plate;
**ax**: horizontal acceleration in feet per second per second, a pitch accelerating away from a right-handed batter has a positive value;
**az**: vertical acceleration;
**pfxx**: horizontal movement or break in inches, difference in final location between that pitch and if that same pitch was thrown with no spin but same speed, a pitch that breaks into a right-handed batter has a positive pfxx value;
**pfxz**: same as pfxx, but vertically with a negative value meaning downward movement;
**spin theta**: the direction in degrees the balls spin towards with 0 degrees being a ball with no horizontal spin/movement and at least some downward movement and top spin, 180 degrees would be upward movement and bottom spin (bottom spin like a fastball);
**rpm**: average spin rate of ball in revolutions per minute, formula for "rpm" and "spin theta/dir" is available here, dividing # by 60 and multiplying by "time" would give the # of revolutions while the ball is in flight;
**x0**,
**z0**: initial coordinates in feet 55 feet from plate, could be approximated as the release point.
**NA**: means the stat is not applicable for this pitcher's pitch because there's not enough data to calculate it.
