Home plate: John Libka
“A steady night's work behind the plate.”
What this shows — how John Libka called the 141 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 132 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+0.13▲5 · 1-1 strike called ball
Isaac Collins vs Davis Martin - 2+0.13▼3 · 1-0 strike called ball
Drew Romo vs Michael Wacha - 3+0.13▼8 · 1-0 strike called ball
Miguel Vargas vs Michael Wacha
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
3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Drew Romo — ump said ball, robot ruled ball: upheld.
- 2Salvador Perez — ump said ball, robot ruled strike: overturned.
- 3Salvador Perez — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
