In fact, we were playing at the University of South Carolina and they had a pitch clock in the outfield that I assume is supposed to be reset by someone in the booth, but you could tell they weren't paying attention 90% of the time so they'd start it at random times.so it didn't mean anything. On the fields that don't have a pitch clock I'm assuming the home plate ump is somehow keeping track, but I don't really see them using a stopwatch or anything. The purpose is to speed up the game so I guess it's ok if they're not following the rule exactly since it doesn't really benefit either team.
