What this shows — how Alfonso Márquez called the 158 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 147 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 · 3 overturned (ump overruled) · 0 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Shea Langeliers — ump said strike, robot ruled ball: overturned.
  2. 2Rafael Marchán — ump said strike, robot ruled ball: overturned.
  3. 3Rafael Marchán — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 0 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
