According to Bill Veeck, one of Rickey's favorite tricks was to offer another team two players and trust that the other team would take the wrong one. In the case of Lee and Heise, Rickey knew that all but one Cubs pitcher was right-handed, and expected the Cubs to take Heise, a left-hander. However, on the advice of chief scout Jack Doyle, the Cubs took Lee.
