PIT @ CWS
Home plate: Alex MacKay
“Down the middle. Both dugouts had the same zone.”
What this shows — how Alex MacKay called the 129 pitches that were taken (no swing), graded against the tracked rulebook strike zone, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 121 were right. Below, only the misses are plotted, alongside every challenged pitch.
The zone, as he called it
The calls that moved the game
- 1+0.23▲4 · 0-2 strike called ball
Bryan Reynolds vs Erick Fedde - 2-0.19▲1 · 2-0 ball called strike
Konnor Griffin vs Hagen Smith - 3+0.13▲2 · 1-1 strike called ball
Jake Mangum vs Hagen Smith
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
2 pitches went to the robots · 0 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Munetaka Murakami — ump said strike, robot ruled strike: upheld.
- 2Andrew Benintendi — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
