What this shows — how Brock Ballou called the 170 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. 149 were right. Below, only the misses are plotted, alongside every challenged pitch.

The zone, as he called it

Challenge 1: Francisco Alvarez — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).1Challenge 2: Bryce Eldridge — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2Challenge 3: Turner Hill — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).3Challenge 4: Francisco Alvarez — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).4Challenge 5: Juan Soto — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).5

ABS — the Automated Ball-Strike System

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

  1. 1Francisco Alvarez — ump said ball, robot ruled strike: overturned.
  2. 2Bryce Eldridge — ump said strike, robot ruled ball: overturned.
  3. 3Turner Hill — ump said strike, robot ruled strike: upheld.
  4. 4Francisco Alvarez — ump said strike, robot ruled ball: overturned.
  5. 5Juan Soto — ump said strike, robot ruled strike: upheld.

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.
