Betting on baseball may have been at its worst in 1919 with the Black Sox scandal, but that doesn't mean it hasn't happened since.
Pete Rose played for the Cincinnati Reds until 1986 and managed the team until 1989, when he was banned for life from baseball, from coaching, and denied his spot in the Baseball Hall of Fame, despite breaking Ty Cobb's record for hits [source: Edwards].
Rose loved baseball, but he had a gambling problem, and he bet extensively not just on baseball, but on his own team. Rose said it was his love of the game that stopped him from confessing sooner and getting help [source: Sports Illustrated]. He was afraid of being banned from professional baseball.
When he was first accused in the late '80s, Rose denied betting on baseball. It wasn't until 2004 -- 15 years later -- that Rose came clean about betting on his own team when he released his tell-all book, "My Prison Without Bars." Cynics felt he made the admission because his last chance to get in the Hall of Fame was December 2005. (He was not voted in.)
In 2007, Rose confessed that he bet on the Reds to win not just occasionally, but on a daily basis [source: CBS]. However, he continues denying he ever bet against his own team,
