Everyone with an account to this site is not the target audience. I’m surprised that the league cut down the time between innings like they did because they reduced their “advertising hole.”
As far as trips to the mound, I’d say that if the coach doesn’t make a gesture to the bullpen within the first 15 seconds of crossing the foul line on his way to the mound (with the exception of assessing an injury–where the umpires are there anyway), then he must keep the current pitcher in the game for at least one more batter. The game gets crazy after the 6th inning when managers are making situational pitching changes and have specialists for each inning. That is the biggest problem with today’s baseball game. I would also make sure the reliever needs to throw his first warm up pitch within 30 seconds of the coach gesturing to the bullpen. You know you are coming in, get your crap together and get to the hill. I think this is why MLB managers are senior citizens–inability to get to the mound quickly
allows for another 10 bullpen warm up pitches. Craziness!!!
