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 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:
hf download tomdoyo/open-command 2026/command_scores.csv --repo-type dataset
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 |
fg_pitching_2025.csv.gz and fg_pitching_2026.csv.gz sit at the root, carrying the FanGraphs season lines command is validated against.
