ABS — the Automated Ball-Strike System
5 pitches went to the robots · 4 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Francisco Alvarez — ump said strike, robot ruled ball: overturned.
- 2Bryce Harper — ump said strike, robot ruled ball: overturned.
- 3Brett Baty — ump said strike, robot ruled ball: overturned.
- 4Bryce Harper — ump said strike, robot ruled strike: upheld.
- 5Francisco Alvarez — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
