WASHINGTON (AP) — The key witness in the Roger Clemens perjury trial testified Monday about three other baseball players who he said took human growth hormone.

Brian McNamee, Clemens’ longtime strength and conditioning coach, told jurors that he provided HGH to current Yankee pitcher Andy Pettitte and former Yankee infielder Chuck Knoblauch. McNamee also testified that former Yankee pitcher Mike Stanton obtained HGH from drug dealer Kirk Radomski, after McNamee put them in touch.

McNamee hadn’t been allowed to name the players before, but U.S. District Judge Reggie Walton said Monday he would allow it to rebut the suggestion made by Clemens’ lawyer during cross-examination that McNamee solely targeted the former pitcher.

Last week, McNamee testified he injected Clemens with steroids and HGH. Clemens, a seven-time Cy Young Award winner, is accused of lying to Congress in 2008 when he denied taking those drugs. Both Pettitte and Knoblauch told congressional investigators that year that McNamee injected them with HGH.

Prosecutors, who hope the information about the three players will help rehabilitate McNamee’s credibility, finished their redirect questioning of McNamee on Monday.

Also Monday, prosecutors put on the stand a Miller-Coors manager who testified about the infamous Miller Lite can that McNamee said he used to store some of the evidence he collected from Clemens, such as syringes and medical waste. The witness, Anthony Manuele, looking at markings on the bottom of the can, was able to confirm that it would have been on shelves between August 2001 and Nov. 15, 2001 — coinciding with the August timeframe that McNamee said he put the items in the can.

Manuele couldn’t resist a little bit of product placement, saying the company pulls the cans from shelves after a certain period because “we want consumers to enjoy the great taste of Miller Lite while it’s still fresh.”

Clemens’ lawyer Rusty Hardin, on cross-examination, needled prosecutors by asking, “You don’t sell these beer cans to keep needles, do you?”

The judge sustained a government objection, but not before Manuele could answer, “No sir.”

The trial is now in its sixth week.
