Former major league star Jack Clark says he will take a lie-detector test about his allegations that Albert Pujols took performance-enhancing drugs — if Pujols will do the same.

Clark a four-time All-Star who played in the majors from 1975 to 1992 made the offer in a letter sent from his attorney to Pujols' legal team STLToday.com reports.

Pujols sued Clark Oct. 4 over comments Clark made Aug. 2 on a radio show he co-hosted on St. Louis' WGNU 920 AM. Clark said he “knew for a fact" that Pujols took performance-enhancing drugs because Pujols' former trainer Chris Mihlfeld told him 10 years ago that he "shot (Pujols) up."

The lawsuit alleges that Clark made "malicious reckless and outrageous falsehoods" that have damaged Pujols' reputation humiliated him and caused him mental anguish and anxiety.
