MLB Catcher Throwing API

Returns catcher, catching-team, or league caught-stealing and throw-quality rows with the public season, game, attempt-threshold, target-base, split-years, team, and roster-membership filters. Table sorting and pagination are applied locally. Catcher rows can be expanded with mlb-statcast-catcher-throwing-details. CSV, charts, and page-local display controls are excluded.

How this endpoint behaves

Returns the first-party Catcher Throwing table for catchers, catching teams, or league totals. Rows include caught-stealing run value, caught-stealing and expected caught-stealing attempts, rate metrics, pop/exchange/flight timing, arm strength, and attempt counts. Sorting and pagination run locally after the source table is fetched. Catcher rows can be expanded with GET /api/v1/mlb/statcast-catcher-throwing-details.
