What this shows — how Lance Barksdale called the 151 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 138 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

6 pitches went to the robots · 4 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Francisco Alvarez — ump said ball, robot ruled strike: overturned.
  2. 2Francisco Alvarez — ump said strike, robot ruled ball: overturned.
  3. 3Lourdes Gurriel Jr. — ump said strike, robot ruled strike: upheld.
  4. 4Francisco Alvarez — ump said strike, robot ruled ball: overturned.
  5. 5Gabriel Moreno — ump said strike, robot ruled ball: overturned.
  6. 6Francisco Alvarez — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
