STL @ SF
Home plate: John Libka
“Solid and unspectacular — exactly what the job asks.”
What this shows — how John Libka called the 151 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 139 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

José Fermín vs Blade Tidwell - 2+0.13▼1 · 1-1 strike called ball
Turner Hill vs Andre Pallante - 3-0.13▼8 · 1-1 ball called strike
Drew Cavanaugh vs Cade Winquest
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 · 2 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Leo Bernal — ump said ball, robot ruled strike: overturned.
- 2Drew Cavanaugh — ump said ball, robot ruled strike: overturned.
- 3Thomas Saggese — ump said strike, robot ruled strike: 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.
