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. He got 121 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+0.23▲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), not our error.
