Questions
How is the data aggregated?
Statcast, batted-ball, and plate-discipline numbers are aggregated from pitch-level tracking data, which starts in 2015 — columns that depend on it are labeled with the first season they exist.
Do I need an account?
No. Leaderboards, player and team pages, ballparks, umpires, the glossary, and the Sandbox Trends tab are all open. Login to customize themes, favorite-team preferences, saved Sandbox views, and the Sandbox Scatterplot and League Trends tabs.
Are my table layouts saved?
Yes, in your browser. Visible columns, column order, heatmaps, and pinned players are stored per page and per tab, with separate layouts for desktop and mobile. They survive reloads and new visits, but they do not follow you to another device.
How far back does the data go?
League-wide season trends in the Sandbox reach back to 1901. Player and team pages cover the modern era, and anything Statcast-derived — expected stats, exit velocity, barrels, swing and chase rates — begins in 2015.
How often is it updated?
A nightly job ingests the previous day's games, so stats, leaderboards, and standings reflect completed games through yesterday. The footer of every page shows the last successful update.
What is the shadow zone?
The band of pitches within about two inches of the strike-zone edge, inside or outside. Those are the calls umpires actually get wrong, so scoring them separately keeps easy pitches down the middle from flattering everyone's accuracy.
