When using the on-deck circle makes absolutely no sense
If you're the on-deck batter, and the bases are loaded with two outs in a tie game in the bottom of the ninth inning, do you go stand in the on-deck circle? There is, of course, no chance you will get to bat. You can't. It's impossible. The hitter will either make an out, and end the inning, or do literally anything else, and end the game. I don't need to explain these facts to you. The question is, do I need to explain these facts to major leaguers?
