I know there are some good umpires on this board who will likely be offended by what I’m about to say. So I will apologize to them in advance.
Back in the day dialogue between players and umpires was part of the game. It was an everyday thing and as a player I really enjoyed it. As long as it was done with respect you could ask where the strike was that day or if a particular pitch was down or out. I don’t know how things have changed so much but today so many umpires think they are beyond reproach. They have huge chips on their shoulders and are looking for any opportunity to assert their authority. My understanding is that many have been trained to think that way. Personally I can’t stand it. Nobody goes to a baseball game to see an umpire. The very best umps are very unassuming IMO. I think the ejection in question is absolutely ridiculous and a perfect example of the current attitude of so many umpires who try to make the game about them.
