What this shows — how Brock Ballou called the 150 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 136 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

7 pitches went to the robots · 4 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Luis Torrens — ump said ball, robot ruled ball: upheld.
  2. 2Liam Hicks — ump said ball, robot ruled strike: overturned.
  3. 3Luis Torrens — ump said ball, robot ruled strike: overturned.
  4. 4Liam Hicks — ump said strike, robot ruled ball: overturned.
  5. 5Liam Hicks — ump said ball, robot ruled strike: overturned.
  6. 6Jakob Marsee — ump said strike, robot ruled strike: upheld.
  7. 7Griffin Conine — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 6 of 7 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
