ATL @ SD
Home plate: Dan Merzel
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Dan Merzel called the 182 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 174 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
- 1-0.20▲9 · 2-1 ball called strike
Drake Baldwin vs Mason Miller - 2+0.19▼2 · 2-0 strike called ball
Fernando Tatis Jr. vs JR Ritchie - 3+0.13▼2 · 1-0 strike called ball
Xander Bogaerts vs JR Ritchie
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 · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Drake Baldwin — ump said ball, robot ruled ball: upheld.
- 2Matt Olson — ump said strike, robot ruled strike: upheld.
- 3Rodolfo Durán — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
