The 2004 Kansas City Royals season was a season in American baseball. It involved the Royals finishing fifth in the American League Central with a record of 58 wins and 104 losses. It was one of the most disappointing seasons in Royals' history. The team had been picked by many sporting magazines to win the AL Central following their third-place finish in 2003. Injuries of veteran acquisitions did the Royals in. Catcher Benito Santiago and outfielder Juan González both played very few games for the boys in blue. Mike Sweeney was also injured during the campaign. As a result, the Royals set a new record for most losses in franchise history.
