NEW YORK – Roger Clemens' ex-trainer has sued the former star pitcher for defamation.
In the lawsuit filed Friday in federal court in Brooklyn, Brian McNamee accused Clemens of launching a public campaign to discredit him after the trainer claimed Clemens used steroids.
McNamee has told federal agents, baseball investigator George Mitchell and a House committee that he injected Clemens more than a dozen times with steroids and human growth hormone from 1998 through 2001. Clemens has denied using performance-enchancing drugs.
Clemens' attorney did not immediately respond to a phone message.
The lawsuit seeks unspecified damages.
