At least we know who won't be committing perjury tomorrow in the Roger Clemens-Brian McNamee steroids case. Yesterday, Clemens' former teammate and good friend Andy Pettitte was granted permission to opt out of testifying against Clemens in front of Congress, probably because his affidavit more closely corroborates McNamee's version of the story than it does Clemens'.

In a February 4 deposition, Pettitte, who has admitted to using human growth hormone (for two days, because his elbow was hurt, and before it was banned by MLB), supposedly said he asked McNamee back in 2002, "How come you don't give me the stuff you give Roger?" to which McNamee replied, "Because it's illegal." Clemens doesn't deny that the conversation occurred, but claims that Pettitte was actually talking about plain old medication, not steroids or HGH. A simple misunderstanding between veteran trainer and veteran professional baseball player, you see!

Now, some might think that Pettitte's decision to refrain from testifying at the hearing reflects poorly on pal Clemens given that, you know, you're not allowed to lie under oath. Clemens' lawyer, Rusty Hardin, however, says "it would be a huge mistake to assume that."

Mitchell Report-named former Yankee Chuck Knoblauch and former Mets trainer/sentenced steroid-distributor Kirk Radomski have also been excused from testifying tomorrow morning, which makes the festivities a mano y mano Clemens-NcNamee showdown. Unfortunately for Clemens, most of the lingering questions still put the heat on him. Why would McNamee lie about Clemens' use of performance-enhancing drugs, but not Pettitte's? Why did Clemens refuse to meet with former Senator George Mitchell? Why did his lawyer not deny that his wife took HGH before a 2003 Sports Illustrated bikini shoot? Why does everyone seem to have "forgotten" what happened between 1998 and 2003 except Clemens?

Tomorrow, we (maybe) find out.

Apropos of nothing, 7 train-loving former pitcher John Rocker has also come out and said that not only did he use steroids in 2000, but that MLB Commish Bud Selig knew about it. Clearly, he didn't call that Asian driver a "stupid bitch" because he's a racist prick. It was 'roid rage!
