PHI @ SD
Home plate: David Rackley
“A steady night's work behind the plate.”
What this shows — how David Rackley called the 152 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 147 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+0.23▼2 · 0-2 strike called ball
Rodolfo Durán vs Jesús Luzardo - 2-0.13▲9 · 1-0 ball called strike
Brandon Marsh vs Yuki Matsui - 3+0.10▼7 · 0-1 strike called ball
Ty France vs Orion Kerkering
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 · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Bryce Harper — ump said strike, robot ruled ball: overturned.
- 2Ty France — ump said strike, robot ruled strike: upheld.
- 3Rafael Marchán — ump said ball, robot ruled ball: upheld.
- 4Xander Bogaerts — 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.
