What this shows — how Mark Ripperger called the 159 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 150 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. 1Victor Caratini — ump said ball, robot ruled strike: overturned.
  2. 2Carter Jensen — ump said ball, robot ruled strike: overturned.
  3. 3Victor Caratini — ump said ball, robot ruled ball: upheld.
  4. 4Victor Caratini — ump said ball, robot ruled strike: overturned.
  5. 5Bobby Witt Jr. — ump said strike, robot ruled ball: overturned.
  6. 6Victor Caratini — ump said strike, robot ruled strike: upheld.
  7. 7Carter Jensen — ump said ball, robot ruled ball: 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.
