Identify a ball, review the landing, and record the section. Save evidence with each observation.

Saved on this browser/device. Export a backup to move reviews into the SQLite database. Reviewed sections do not imply surveyed seat positions; older footage needs the matching park configuration.
Field anchors first, then section identifiers, row ranges, bullpens, netting and distinctive landmarks. Roof coverings stay hidden so the seats remain accessible.
FiveThirtyEight’s 2019 sample has 906 events. Only its camera-confirmed zones are retained in our seed file. These records lack pitch identities and seating sections, so they do not enter seat rankings.
Inspect the seed data ↗Exit velocity, vertical launch angle, projected distance and event context support modeling. The inspected pages do not provide a measured spectator-seat XYZ endpoint for each foul or home run.
Savant field definitions ↗Work park by park, beginning with 2017–2026. Review publicly available clips, keep unseen landings unknown, record nets by year, and have a second reviewer check section identifications before publishing.
