The Rules of Baseball in Ten Minutes
Never watched a game in your life? Start here. Everything you need to follow an inning, in plain language.
The Field: A Tour of the Diamond
Before the rules make sense, you need the map. Home plate, the bases, the mound, fair and foul — where everything lives.
How an At-Bat Works: Balls, Strikes, and the Count
The duel at the heart of the game — what the strike zone is, how the count works, and the two ways an at-bat ends.
The Nine Positions and What They Do
Pitcher, catcher, four infielders, three outfielders. A quick tour of who stands where, and why it matters.
Once you understand the game, see what the model sees.
Nine engines deliberate before first pitch and publish a single worked analysis to a permanent public ledger. Every call is graded the next morning — wins and losses both stay, so you can learn from each one.
