Run Game
Adjusted MLB pitcher hold, catcher throwing, runner value, count windows, framing, and ABS challenge leaderboards.
Between the Bases
Who locks down the basepaths?
The Run Game Engine assigns credit to each base running event, to curate a summary of how each player responds to, or controls, the running game.
Run Game Engine
Every foot between the bases, broken down
Pitcher hold, catcher throwing, runner selection, pitch-count windows, called-pitch framing, and ABS challenge value are scored independently. Low samples are pulled toward league average.
