Overview
- In the Reds‑Cubs game on Friday, home‑plate umpire Bill Miller had eight ABS challenges overturned and went 0‑for‑8 on reviews.
- Also on Friday, Alan Porter Jr. had nine calls reversed in the Giants‑Diamondbacks game, a total tied for the second‑most overturned by a single umpire this season.
- The late‑August showings add to a season pattern that includes Clint Vondrak’s 11 overturned calls in a 16‑challenge June game and earlier multi‑overturn nights for C.B. Bucknor and Andy Fletcher.
- Those games produced on‑field consequences including ejections and a hot‑mic tirade from a Reds reliever who later apologized, highlighting growing player frustration with disputed ball‑strike rulings.
- Independent trackers are cataloging overturn totals and the ABS continues to operate leaguewide, increasing scrutiny on umpires’ strike‑zone consistency and raising pressure on MLB to monitor or improve officiating practices.
