Pujols is suing Clark, who played for the Cardinals from 1985 to 1987, for his comments on a local radio show accusing Pujols of using steroids. Clark’s lawyer, Al Watkins, suggested Monday both men take polygraph tests.

Pujols, a nine-time All-Star who played for the Cardinals from 2001-11, filed a defamation lawsuit against Clark in St. Louis County, seeking unspecified damages that would be donated to charity.

The St. Louis Post-Dispatch reports Martin Singer, Pujols’ lawyer in Los Angeles where the slugger plays for the Angels, says sworn testimony, “not inadmissible polygraphs and absurd publicity ploys — is what counts.”
