SEA @ STL
Home plate: Edwin Moscoso
“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Edwin Moscoso 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+0.30▼4 · 3-1 strike called ball
Alec Burleson vs George Kirby - 2+0.20▲4 · 2-1 strike called ball
Josh Naylor vs Andre Pallante - 3-0.20▲6 · 2-1 ball called strike
Rob Refsnyder vs Justin Bruihl
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.
- 1Cal Raleigh — ump said ball, robot ruled strike: overturned.
- 2Luke Raley — ump said strike, robot ruled ball: overturned.
- 3Josh Naylor — 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.
