Baseball star Albert Pujols is suing former Cardinals slugger Jack Clark for saying on his radio show that Pujols used steroids.

The St. Louis Post-Dispatch (http://bit.ly/1cd96kN ) reports that the lawsuit filed Friday in St. Louis County seeks unspecified damages and asks for a declaration that Clark's statements are false.

Clark said during his show on WGNU on Aug. 2 that he knew "for a fact" that Pujols used steroids and performance enhancing drugs. Clark and co-host Kevin Slaten were fired soon afterward.

The lawsuit says Clark's comments are lies that have damaged Pujols' reputation, causing him humiliation, mental anguish and anxiety.

Clark's attorney, Chet Pleban, says Clark will welcome a jury trial. Pujols now plays for the Los Angeles Angels after 11 years in St. Louis.
