In the middle of the ninth inning, the pitcher tells the infield that they're going to play a game of "defense" with a runner on third. The infield moves toward home base, and the pitcher knows that the runner is going to try to squeeze the first pitch. He's going to watch the batter closely, and if the batter does try to hit it, he'll be punished. The pitcher says that if they don't play the game, he won't feel satisfied, because he's never going to feel satisfied until he stands on a stage like this one.
