BEQ_R

[ Details ] [ Return To Top ]

Bequeathed runners who scored.

FLAKE

[ Details ] [ Return To Top ]

Standard deviation of per-start SNVA for each pitcher. This was previously shown as the variance, and was used to compute the "flakiest" pitchers. Standard deviation is just the square root of the variance, so these are equivalent.

FRA

[ Details ] [ Return To Top ]

See FRA

GS

[ Details ] [ Return To Top ]

Games started by a pitcher.

IP

[ Details ] [ Return To Top ]

Innings Pitched.

L

[ Details ] [ Return To Top ]

Refers to a pitcher's losses. In context of a team rather than an individual pitcher, refers to team losses.

LG

League. 'A' or 'AL' denotes American League. 'N' or 'NL' denotes National League.

LUCK

[ Details ] [ Return To Top ]

Luck, as measured by the number of extra wins, and short losses the pitcher actually got, versus his expected record. LUCK = (W-E(W))+(E(L)-L)

NAME

[ Details ] [ Return To Top ]

Player's name.

Pen Support

[ Details ] [ Return To Top ]

The number of additional runs charged to the starting pitcher that his bullpen allowed to score after he left the game, compared to an average bullpen. Negative Pen Support means the bullpen prevented more runs from scoring than an average pen (i.e. the pitcher's ERA looks better than it should because of good bullpen support).

[ Details ] [ Return To Top ]

Actual team runs allowed. Can also stand for Run Average--runs allowed, earned or otherwise, divided by innings pitched, times 9.

Support-Neutral Lineup-adjusted Value Added - like SNVA, but also adjusted for the MLVr of each batter the pitcher faced.

SNLVAR

[ Details ] [ Return To Top ]

like SNLVA, but comparing to replacement level, rather than average. Replacement level is now being computed the same way in SNVA and in VORP (using the formulas from Keith Woolner's BP 2002 article).

SNVA

[ Details ] [ Return To Top ]

Support-Neutral Value Added - wins above average added by the pitcher's performance.

SNVAR

[ Details ] [ Return To Top ]
