DET @ AZ
Home plate: Todd Tichenor
“The kind of night where the umpire is the least of the story.”
What this shows — how Todd Tichenor called the 197 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 183 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

Carlos Santana vs Justin Verlander - 2+0.13▼1 · 1-1 strike called ball
Geraldo Perdomo vs Justin Verlander - 3+0.13▼5 · 1-1 strike called ball
Carlos Santana vs Enmanuel De Jesus
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
3 pitches went to the robots · 2 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Dillon Dingler — ump said ball, robot ruled strike: overturned.
- 2Dillon Dingler — ump said ball, robot ruled strike: overturned.
- 3Spencer Torkelson — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
