Situation: 1980 World Series, Kansas City vs. Philadelphia
Injury: Hemorrhoids
What happened: While causing him to be the butt of jokes to some, Bretts condition was so bad that the Royals third baseman could play in only five innings of Game 1 against the Phillies and was unable to sit on the bench during the game. Between Games 2 and 3, Brett had an operation to relieve the condition and was able to finish the series. In six games, he batted .375 with a homer, three RBIs and a stolen base, though the Phillies won the series. (Stephen Dunn / Getty Images)
