I don't remember that one but I used Gemini to summarize all the variants of unintentional or accidental ABS challenges. This is going to be a problem if it's not fixed soon.
I haven't checked in detail if all these are correct so just FYI:
The Pitcher Tic and Misinterpreted Signal are the 2 that I saw
The Frustration Tap: A player taps or grabs their helmet as a reflex of being upset (like Ben Rice), which the umpire is required to interpret as a challenge.
The Pitcher’s Tic: A pitcher instinctively adjusts their cap or wipes their brow (like Bubba Chandler) within the 2-second window, unintentionally triggering the sensor or umpire’s attention.
The Reflexive Double-Fail: A hitter challenges a pitch before hearing the call (like Jordan Westburg), only to find out the umpire called it a ball. Because it cannot be retracted, they "lose" the challenge because the call was already correct.
The Misinterpreted Signal: A teammate (often the catcher or the next batter) taps their head thinking their teammate wants to challenge, accidentally burning the team’s timeout (like Will Smith/Shohei Ohtani).
The Panic Challenge: Challenging a pitch that is clearly a strike (sometimes by several inches) out of desperation in a high-leverage count, often referred to as a "throwaway" or "worst challenge."
The Gear Adjustment: Simple equipment maintenance—like tightening a chin strap or pulling down a brim—that happens to fall within the strict 2-second post-pitch window.
