Last night in two separate games, two catchers got thrown out of the game after the homeplate umpires missed called strikes. I can't remember the last time I saw one catcher thrown out of a game while catching. Catchers and umpires usually get along well, and I always thought that catchers could say a lot as long as they didn't "show up" the umps by turning around.
In addition to the two catches, a bunch of other managers and players got thrown out by umpires. In every case, the umps inflamed the arguments by being confrontational even following managers as they walked away.
In no other sport does an official instigate arguments. NFL refs don't even look at the coaches and players when they argue, and NBA refs despite being so inept manage to stay calm no matter how heated the player gets over a bad call.
Most arguments do start when the umpire or ref makes a bad call, so they look even more foolish as they inflame the arguments.
