Part III: Formulas and Definitions
PA = (AB + BB + HBP + SF + SH + defensive interference)
Total Bases = [H + 2B + (2 X 3
+ (3 X HR)]
AVG = H/AB
OBP = (H + BB + HBP)/(AB + BB + HBP + SF)
SLG = TB/AB
Part IV: Breakdown Categories
Ahead/Behind in Count
For hitters, ahead in count includes 1-0, 2-0, 3-0, 2-1 and 3-1.
Behind in count for hitters includes 0-1, 0-2, 1-2 and 2-2.
The opposite is true for pitchers.
Day/Night
Officially, night games in the National League are those that start after 5:00 pm, while night games in the AL begin after 6:00 pm. Therefore, a game at 5:30 in Yankee Stadium is a day game while one in Shea Stadium at the same time is a night game. We avoid this silliness by calling all games starting after 5:00pm night games.
First Pitch
Refers to the first pitch of a given at bat, and any walks listed here are intentional walks.
Grass/Turf
Grass is grass. Turf is artificial turf.
Groundball/Flyball Ratio
A hitter's stats against pitchers that induce mostly grounders or flies, respectively. If the ratio is less than 1.00, then he is a Flyball hitter. If it is greater than 1.50, he is a Groundball hitter. Anything else is classified as neutral. Same cutoffs apply for classifying pitchers. Anyone with less than 50 plate appearances is automatically neutral.
First Inning Pitched
Describes the result of the pitcher's work until he recorded three outs.
Inning 1-6 and Inning 7+
There refer to the actual innings in which a pitcher worked.
None On/Out
Refers to situation when there are no outs and the bases are empty (generally leadoff situations).
None On/Runners On
Describes the status of the baserunners
Number of Pitches
This section shows the results of balls put into play while his pitch count was in that range.
Pitcher/Batter Match-Ups
The following conditions must be met before a player is added to the list:
a) There must be greater than 10 plate appearances between the batter and the pitcher; and
b) Batters must have a .300 average against a pitcher to be considered a "Hits Best Against" candidate, and pitchers must limit hitters to under .250 to be listed under "Pitches Best Vs."
Thus, not all hitters will have five pitchers that qualify and not all pitchers will have five batters who qualify.
Scoring Position
At least one runner must be at either second or third base.
Vs. 1st Batter (Relief)
Describes what happened to the first batter a reliever faces.
