PIT @ MIL
Home plate: John Libka
“A small strike zone, generously enforced for the offense.”
What this shows — how John Libka called the 171 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 160 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
Brandon Lowe vs Chad Patrick - 2+0.13▼2 · 1-1 strike called ball
Jake Bauers vs Bubba Chandler - 3+0.13▲6 · 1-0 strike called ball
Jake Mangum vs Garrett Stallings
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
5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Henry Davis — ump said strike, robot ruled ball: overturned.
- 2William Contreras — ump said ball, robot ruled ball: upheld.
- 3Henry Davis — ump said ball, robot ruled ball: upheld.
- 4Cooper Pratt — ump said strike, robot ruled strike: upheld.
- 5Henry Davis — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
