PHI @ BOS
Home plate: Dan Merzel
“A workmanlike night — nothing to frame, nothing to fix.”
What this shows — how Dan Merzel called the 131 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 125 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
- 1-0.13▲4 · 1-1 ball called strike
J.T. Realmuto vs Brayan Bello - 2-0.13▼8 · 1-0 ball called strike
Mickey Gasper vs José Alvarado - 3+0.10▼7 · 0-1 strike called ball
Trevor Story vs Zack Wheeler
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
2 pitches went to the robots · 1 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Alec Bohm — ump said strike, robot ruled ball: overturned.
- 2Adolis García — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 2 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
