What this shows — how Dan Bellino called the 153 pitches that were taken (no swing), graded against the tracked rulebook strike zone, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 139 were right. Below, only the misses are plotted, alongside every challenged pitch.

The zone, as he called it

Challenge 1: Bo Bichette — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1Challenge 2: Francisco Alvarez — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2Challenge 3: Carlos Narváez — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).3Challenge 4: Francisco Alvarez — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).4Challenge 5: Marcus Semien — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).5

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

5 pitches went to the robots · 4 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Bo Bichette — ump said strike, robot ruled ball: overturned.
  2. 2Francisco Alvarez — ump said ball, robot ruled strike: overturned.
  3. 3Carlos Narváez — ump said ball, robot ruled ball: upheld.
  4. 4Francisco Alvarez — ump said ball, robot ruled strike: overturned.
  5. 5Marcus Semien — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 5 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
