COL @ STL
Home plate: Willie Traynor
“A steady night's work behind the plate.”
What this shows — how Willie Traynor called the 185 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 173 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
- 1-0.21▲6 · 3-0 ball called strike
Ezequiel Tovar vs Luis Gastelum - 2-0.20▼6 · 2-1 ball called strike
Alec Burleson vs Parker Mushinski - 3+0.19▲1 · 2-0 strike called ball
Kyle Karros vs Matthew Liberatore
Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.
ABS — the Automated Ball-Strike System
4 pitches went to the robots · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Matthew Liberatore — ump said ball, robot ruled ball: upheld.
- 2Willi Castro — ump said strike, robot ruled strike: upheld.
- 3Willi Castro — ump said strike, robot ruled strike: upheld.
- 4Everson Pereira — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
