PHI @ SF
Home plate: Clint Vondrak
“A steady night's work behind the plate.”
What this shows — how Clint Vondrak called the 146 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 138 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
- 1-0.13▼8 · 1-1 ball called strike
Harrison Bader vs Orion Kerkering - 2-0.13▼1 · 1-0 ball called strike
Willy Adames vs Cristopher Sánchez - 3+0.13▲6 · 1-0 strike called ball
Bryce Harper vs Robbie Ray
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
1 pitch went to the robots · 1 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Jerar Encarnacion — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 0 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
