KC @ BOS
Home plate: Roberto Ortiz
“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Roberto Ortiz called the 135 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 128 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
John Rave vs Aroldis Chapman - 2-0.20▲9 · 2-1 ball called strike
Tyler Tolbert vs Aroldis Chapman - 3+0.13▼1 · 1-1 strike called ball
Roman Anthony vs Noah Cameron
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.
- 1Nick Sogard — ump said strike, robot ruled strike: upheld.
- 2Adley Rutschman — ump said ball, robot ruled strike: overturned.
- 3Carter Jensen — ump said strike, robot ruled ball: overturned.
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.
