OpenCommand Catcher targets and pitcher command for MLB, inferred from broadcast video. OpenCommand scores command using the pitch location's distance from target. This dataset contains the 2024/2025/2026 computer vision object detections, every intermediate the pipeline writes, and the resulting command scores. The pipeline itself and the full method write-up live at github.com/tomdoyo/open-command.

OpenCommand

Catcher targets and pitcher command for MLB, inferred from broadcast video.

OpenCommand scores command using the pitch location's distance from target.

This dataset contains the 2024/2025/2026 computer vision object detections, every intermediate the pipeline writes, and the resulting command scores. The pipeline itself and the full method write-up live at github.com/tomdoyo/open-command.

Download

hf download tomdoyo/open-command --repo-type dataset --local-dir data

That puts the tree where the pipeline expects it, so any stage re-runs from the code repo:

python src/solve_glove_locations.py 2026

One file instead of the whole tree:

Data

Each season lives under <year>/.

Keys: (game_pk, play_id) identify a pitch.

Raw detections (in <year>/raw/) are produced using YOLO11 glove/ball/strikezone detector models, with postprocessing based on detection confidence.

File (per season)	One row per	Contents
`pbp_info.csv.gz`	pitch	Statcast 9-parameter trajectory, `sz_top`/`sz_bot`, plate location, pitcher, pitch type, and the game_date/type/venue
`raw/gloveball_tracks/<game_pk>.csv.gz`	frame	glove + ball detections (pixels on screen)
`raw/strikezone_tracking.csv.gz`	clip	broadcast strikezone detections (pixels on screen)
`camera_poses.csv.gz`	clip	camera pose (+ vote diagnostics & reprojection accuracies)
`glove_locations/<game_pk>.csv.gz`	detection	solved glove location (real-world)
`targets.csv.gz`	clip	naive/inferred targets
`command_scores.csv`	pitcher, pitch type	n, naive and inferred median miss

fangraphs/fg_pitching_<year>.csv.gz carries the FanGraphs season lines command is validated against.
