Pettitte told congressional lawyers that Clemens informed him nearly a decade ago he had used human growth hormone and said McNamee let him know in 2003 or 2004 that Clemens had used steroids. Pettitte also admitted his own use of HGH was not limited to 2002, as he previously said, but that he also took injections in 2004 after obtaining the substance from his ailing father.
McNamee, personal trainer for Clemens and Pettitte, said in the Mitchell Report that Clemens used steroids and HGH, an accusation the seven-time Cy Young Award winner denies. McNamee also said Pettitte used HGH.
On Dec. 15, two days after the Mitchell Report was released, Pettitte said he used HGH for two days in 2002 while with the New York Yankees. Last week, he went further, in a deposition for congressional investigators and an affidavit submitted in exchange for being excused from Wednesday's hearing.
"In 2004, when I tore the flexor tendon in my pitching arm, I again used HGH two times in one day out of frustration and in a futile attempt to recover. Unfortunately," Pettitte said in his affidavit.
Pettitte's lawyers said he will speak publicly when he arrives at spring training with the Yankees.
In his affidavit, Pettitte said Clemens acknowledged to him long ago that he used HGH.
"In 1999 or 2000, I had a conversation with Roger Clemens in which Roger told me that he had taken human growth hormone. ... He did not tell me where he got the HGH or from whom, but he did tell me that it helped the body recover," the affidavit said. Clemens was asked whether he considers Pettitte an honest person, and Clemens said yes.
"Andy Pettitte is my friend. He was my friend before this. He will be my friend after this and again. I think Andy has misheard," Clemens said. "I think he misremembers."
