The Chicago Cubs and St. Louis Cardinals are arguably the fiercest rivals in the history of baseball, if not the history of sport. Jay Hanna "Dizzy" Dean is one of the few baseball players that experienced both sides of that rivalry. As the anchor for the Cardinals’ pitching staff, Dean earned four consecutive strikeout titles, led the National League in complete games for four consecutive seasons, and won two games in the 1934 World Series. The Cardinals championship in 1934 was kept in the family as Paul "Daffy" Dean, Dizzy’s younger brother, won the other two games of the World Series. Dizzy’s career in Chicago lacked the brilliance he conveyed in St. Louis, due in part to an injury suffered in the 1937 All-Star game. His toe was broken by a line drive off the bat of Earl Averill. Dean altered his pitching motion to compensate for the broken toe, injuring his throwing arm in the process. Dean last played in 1947, pitching a four inning shutout for the St. Louis Browns. The four-time 20-game winner was elected to baseball’s Hall of Fame in 1953.
