By hitting 40 home runs and stealing 40 bases in a single season, Jose Canseco, Barry Bonds, Alex Rodriguez, and Alfonso Soriano became the elite and exclusive members of this record-setting club. The first four members of the club played for the Oakland Athletics while Soriano joined them on the Chicago Cubs. The 40-40 Club is so named because each member has hit 40 home runs and stolen 40 bases in a single season. The only other players to do so are Rogers Hornsby (100 games in 1924) and Joe DiMaggio (56 games in 1941). Besides being a great hitter who led the American League in homers six times, Hornsby was also a superb fielder who made three appearances in the 1920 World Series without recording an out. He was voted the Most Valuable Player of the Series after leading the New York Yankees to their first championship in 22 years. DiMaggio was one of the most popular players in baseball during his time due to his exceptional batting skills and his role as "Mr. October". He established himself as a force to be reckoned with early in his career when he led the American League in hits twice (1934, 1935). In 1937, his final season before retiring, DiMaggio was considered one of the best hitters in baseball.
