Home plate: Lance Barrett
“Hawkeye clocked in early and stayed late.”
What this shows — how Lance Barrett called the 152 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 141 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
The zone, as he called it
The calls that moved the game
- 1+0.28▲9 · 1-2 strike called ball
Ian Happ vs Juan Burgos - 2-0.21▲1 · 3-0 ball called strike
Michael Busch vs Merrill Kelly - 3-0.20▼2 · 2-1 ball called strike
Nolan Arenado vs Kevin Gausman
Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.
