✓ boot: exhibition opens at the top of the first, you hold the ball
✓ the other dugout is fully staffed: an arm with habits, nine bats
✓ the tape threw a real pitch: select, aim, meter, flight
✓ flight math: every pitch lands at aim plus its own bite, exactly
✓ the sight cannot lie: the mark you stop is the height it crosses
✓ a stopwatch is not an eye: the sweep starts somewhere you can't know
✓ the sight is honest about its ends: center is free, the ends cost full
✓ the nastier the pitch, the twitchier the arm: sweeps rank by bite
✓ the chart only remembers pitches that finished, and only this half
✓ the clock is a sample, not an answer: nothing scouted before you bat
✓ the tell is real: windups differ by pitch and the change hides short
✓ swing eval: pure timing is a hit, a wild hack is a whiff, the edge fouls
✓ under the ball lifts it, over the ball beats it into the ground
✓ early is a pull: the spray sign matches the field it names
✓ power narrows the window and pays in exit velocity
✓ a homer clears every base including the batter
✓ a single pushes the line along one station
✓ the wall is real: no landing spot resolves beyond it
✓ the best play in the game also has to DRAW: homer, confetti and all
✓ fast win is a bug: nothing completes at boot
