Home plate: Alex MacKay
“A workmanlike night — nothing to frame, nothing to fix.”
What this shows — how Alex MacKay called the 189 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 181 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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.
- 1Vinnie Pasquantino — ump said strike, robot ruled ball: overturned.
- 2Travis d'Arnaud — ump said ball, robot ruled ball: upheld.
- 3Carter Jensen — ump said ball, robot ruled ball: upheld.
- 4Bryce Teodosio — 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.
