BAL @ DET
Home plate: Chad Whitson
“The kind of night where the umpire is the least of the story.”
What this shows — how Chad Whitson called the 149 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 140 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
The calls that moved the game
- 1-0.21▼4 · 3-0 ball called strike
Kevin McGonigle vs Dean Kremer - 2+0.13▲6 · 1-0 strike called ball
Pete Alonso vs Troy Melton - 3+0.10▼8 · 0-1 strike called ball
Kevin McGonigle vs Chadwick Tromp
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
4 pitches went to the robots · 3 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Yohel Pozo — ump said strike, robot ruled ball: overturned.
- 2Eduardo Valencia — ump said strike, robot ruled ball: overturned.
- 3Yohel Pozo — ump said ball, robot ruled ball: upheld.
- 4Coby Mayo — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 1 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
