“A steady night's work behind the plate.”
What this shows — how Alex MacKay called the 169 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 159 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
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.
- 1Juan Brito — ump said strike, robot ruled strike: upheld.
- 2Pedro Pagés — ump said ball, robot ruled strike: overturned.
- 3Rhys Hoskins — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
