STL @ LAA
Home plate: Mark Ripperger
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Mark Ripperger called the 140 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 134 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+0.39▲1 · 2-2 strike called ball
Lars Nootbaar vs Walbert Ureña - 2-0.30▼7 · 3-1 ball called strike
Zach Neto vs Scott Blewett - 3+0.23▼3 · 0-2 strike called ball
Jorge Soler vs Matthew Liberatore
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 · 0 overturned (ump overruled) · 4 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Nolan Schanuel — ump said strike, robot ruled strike: upheld.
- 2Jorge Soler — ump said strike, robot ruled strike: upheld.
- 3Iván Herrera — ump said ball, robot ruled ball: upheld.
- 4Lars Nootbaar — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
