Home plate: Mark Ripperger
“Down the middle. Both dugouts had the same zone.”
What this shows — how Mark Ripperger called the 127 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 121 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▼2 · 2-1 strike called ball
Konnor Griffin vs Ben Brown - 2+0.13▼7 · 1-1 strike called ball
Spencer Horwitz vs Trent Thornton - 3+0.09▲2 · 0-0 strike called ball
Pedro Ramírez vs Carmen Mlodzinski
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 · 0 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Henry Davis — ump said ball, robot ruled ball: upheld.
- 2Seiya Suzuki — 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.
