BOS @ STL
Home plate: Brian Walsh
“ABS had a long evening on this one.”
What this shows — how Brian Walsh called the 156 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 145 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+0.28▲1 · 1-2 strike called ball
Jarren Duran vs Kyle Leahy - 2+0.23▼6 · 0-2 strike called ball
Nolan Gorman vs Ranger Suarez - 3+0.20▲7 · 2-1 strike called ball
Marcelo Mayer vs Gordon Graceffo
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 · 5 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Iván Herrera — ump said strike, robot ruled ball: overturned.
- 2Ramón Urías — ump said strike, robot ruled ball: overturned.
- 3Pedro Pagés — ump said ball, robot ruled strike: overturned.
- 4Jordan Walker — ump said strike, robot ruled ball: overturned.
- 5Yohel Pozo — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
