What this shows — how Alan Porter called the 172 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 151 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

The zone, as he called it

Challenge 1: Ceddanne Rafaela — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).1Challenge 2: Connor Wong — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2Challenge 3: Jorge Polanco — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).3Challenge 4: Anthony Seigler — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).4Challenge 5: Francisco Alvarez — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).5Challenge 6: Jarren Duran — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).6

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 · 4 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Ceddanne Rafaela — ump said strike, robot ruled strike: upheld.
  2. 2Connor Wong — ump said strike, robot ruled ball: overturned.
  3. 3Jorge Polanco — ump said ball, robot ruled strike: overturned.
  4. 4Anthony Seigler — ump said ball, robot ruled strike: overturned.
  5. 5Francisco Alvarez — ump said ball, robot ruled ball: upheld.
  6. 6Jarren Duran — ump said ball, robot ruled strike: overturned.

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.
