Home plate: Chris Guccione
“A small strike zone, generously enforced for the offense.”
What this shows — how Chris Guccione called the 177 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 165 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+0.39▲7 · 2-2 strike called ball
Geraldo Perdomo vs José A. Ferrer - 2+0.13▲1 · 1-0 strike called ball
Ketel Marte vs George Kirby - 3+0.13▼1 · 1-0 strike called ball
J.P. Crawford vs Zac Gallen
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.
- 1Jhonny Pereda — ump said ball, robot ruled strike: overturned.
- 2Jhonny Pereda — ump said ball, robot ruled ball: upheld.
- 3Jhonny Pereda — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
