What this shows — how Sean Barber called the 164 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 154 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 · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Francisco Alvarez — ump said strike, robot ruled strike: upheld.
  2. 2Francisco Alvarez — ump said ball, robot ruled strike: overturned.
  3. 3Christopher Morel — ump said strike, robot ruled strike: upheld.
  4. 4Jacob Young — ump said strike, robot ruled ball: overturned.

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.
