Keep your eye on the ball.
Hear only the things you should hear - be deaf to others.
Avoid sarcasm. Don't insist on the last word.
Baseball is probably the world's best documented sport.
I don’t care if half the league strikes. Those who do will encounter quick retribution. All will be suspended, and I don’t care if it wrecks the league for 10 years. This is the United States of America, and one citizen has as much right to play as another.
Never charge a player and, above all, no pointing your finger or yelling.
