"We do not play baseball. We play professional baseball. Amateurs play games. We are paid to win games. There are rules, and there are consequences if you break them. If you are a pro, then you often don’t decide whether to cheat based on if it’s "right or wrong." You base it on whether or not you can get away with it, and what the penalty might be. A guy who cheats in a friendly game of cards is a cheater. A pro who throws a spitball to support his family is a competitor."
– Former major-league pitcher and manager George Bamberger
