What this shows — how Chris Guccione called the 157 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 152 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

5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Javier Báez — ump said ball, robot ruled strike: overturned.
  2. 2Hunter Feduccia — ump said strike, robot ruled ball: overturned.
  3. 3Spencer Torkelson — ump said strike, robot ruled strike: upheld.
  4. 4Dillon Dingler — ump said strike, robot ruled strike: upheld.
  5. 5Ben Rortvedt — ump said ball, robot ruled ball: 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.
