What this shows — how Alfonso Márquez called the 186 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 171 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

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

  1. 1Sebastián Rivero — ump said ball, robot ruled ball: upheld.
  2. 2Nick Fortes — ump said ball, robot ruled ball: upheld.
  3. 3Sebastián Rivero — ump said ball, robot ruled ball: upheld.
  4. 4Taylor Walls — ump said ball, robot ruled strike: overturned.
  5. 5Nick Fortes — ump said strike, robot ruled ball: overturned.
  6. 6Nick Fortes — 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.
