“Reliable as a Tuesday: no complaints, no headlines.”
What this shows — how Alan Porter called the 153 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 145 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

ABS — the Automated Ball-Strike System
4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Drake Baldwin — ump said ball, robot ruled strike: overturned.
- 2Matt Olson — ump said strike, robot ruled strike: upheld.
- 3Drake Baldwin — ump said ball, robot ruled strike: overturned.
- 4Pedro Pagés — ump said ball, robot ruled ball: 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.
