Clemens' Attorney Changing Ways to Serve McNamee

Offense has been Roger Clemens' defense these past few weeks, and the seven-time Cy Young Award winner took another shot Thursday at Brian McNamee in his continuing effort to discredit his former personal trainer.

Clemens' attorney, Rusty Hardin, released a "motion for substituted service" to show that Clemens has been unsuccessful in his attempt to physically serve McNamee -- who told federal agents and baseball steroids investigator George Mitchell that he injected steroids and human growth hormone into Clemens -- the papers for his defamation lawsuit, which was filed Jan. 6.
