 Because Koufax's signing bonus was greater than $ 4,000 ($ 35,000 today), he was known as a bonus baby. This forced the Dodgers to keep him on the major league roster for at least two years before he could be sent to the minors. To make room for him, the Dodgers optioned their future Hall of Fame manager, Tommy Lasorda, to the Montreal Royals of the International League. Lasorda would later joke that it took Koufax to keep him off the Dodger pitching staff.
