Home plate: Alex MacKay
“The catcher barely had to sell a thing.”
What this shows — how Alex MacKay called the 114 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 110 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

Victor Mesa Jr. vs Tanner Gordon - 2-0.09▲1 · 0-0 ball called strike
Yandy Díaz vs Michael Lorenzen - 3-0.09▼1 · 0-0 ball called strike
Kyle Karros vs Ian Seymour
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
4 pitches went to the robots · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Hunter Goodman — ump said strike, robot ruled ball: overturned.
- 2Kyle Karros — ump said strike, robot ruled strike: upheld.
- 3Willi Castro — ump said strike, robot ruled strike: upheld.
- 4Chandler Simpson — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
