CIN @ SF
Home plate: Chris Conroy
“The kind of night where the umpire is the least of the story.”
What this shows — how Chris Conroy called the 137 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 134 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
