There are up to 8 games going on at a time. When some player says “did you see what so and so said to that ump”. I immediately ask “did he get ejected”?
If the answer is no. Then we can look at the stationary camera livestream and try to listen etc but if it wasn’t bad enough for the ump to eject then its a pretty big stretch for a utrip official to take it the next step which is suspension.
