What this shows — how Dan Merzel called the 153 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 140 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

- 2Rafael Marchán — ump said ball, robot ruled strike: overturned.
- 3Rafael Marchán — ump said ball, robot ruled ball: upheld.

- 5Justin Crawford — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
