SF @ PIT
Home plate: Todd Tichenor
“The zone kept to itself — the hitters said thanks.”
What this shows — how Todd Tichenor called the 208 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 190 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▲6 · 3-1 strike called ball
Bryce Eldridge vs Yohan Ramírez - 2+0.30▲8 · 3-1 strike called ball
Jonah Cox vs Evan Sisk - 3+0.28▲2 · 1-2 strike called ball
Osleivis Basabe vs Paul Skenes
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
5 pitches went to the robots · 2 overturned (ump overruled) · 3 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 strike: overturned.
- 2Drew Cavanaugh — ump said ball, robot ruled strike: overturned.
- 3Drew Cavanaugh — ump said ball, robot ruled ball: upheld.
- 4Jacob Gonzalez — ump said strike, robot ruled strike: upheld.
- 5Spencer Horwitz — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 5 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
