An important witness in the federal perjury trial of former baseball ace Roger Clemens could testify, according to a prosecutor.

Brian McNamee, Clemens’ former personal trainer, could testify, Prosecutor Steven Durham told U.S. District Court Judge Reggie Walton.

From Reuters.com:

McNamee’s claims that Clemens, 49, used anabolic steroids and human growth hormone during his 24-year career are at the center of the government’s charges that the pitcher lied to Congress about drug use.

Durham has alleged that McNamee injected Clemens with anabolic steroids in 1998, 2000 and 2001 and with human growth hormone in 2001.

Clemens has denied allegations he used performance-enhancing drugs. His defense attorneys have called McNamee a liar.

Former Internal Revenue Service agent Jeff Novitsky, who had investigated McNamee as part of a probe into performance-enhancing drugs, testified on Thursday about evidence obtained during the investigation.

Clemens is among one of the biggest baseball stars linked to alleged drug use.
