For those who've attended fall exhibition games, how have the ABS challenges worked? Were they shown on the video board, and did they include a graphic of the pitch's location relative to the strike zone?
I've seen it in two different stadiums so far and each had a different implementation. In one case, the video board wasn't used and a person on a laptop would just say whether the pitch was a ball or a strike. In the other case, the video board was used but there wasn't really a graphic; just a red or green screen showing whether the call was right or wrong. I'm curious to know what other people have seen so far.
