Then, under cross-examination from one of Clemens' lawyers, Pettitte revealed how tenuous his account might seem to the jury. Attorney Michael Attanassio asked if it came amid a "lot of huffing and puffing" that accompanies a workout.
"Yes," Pettitte answered.
Pettitte testified mostly with his hands clasped in front of him and rarely looked at Clemens, even during the lengthy delays when lawyers held conferences at the judge's bench. Clemens frequently took notes. The two haven't spoken recently because of the trial, but Pettitte nevertheless said he found it difficult to testify because he still considers Clemens a good friend.
Pettitte was then asked if Clemens' remark was made "in passing" -- as opposed to in a "focused conversation."
"I would say so," Pettitte said.
Pettitte will return to the stand on Wednesday.
Pettitte also recalled the other time he spoke with Clemens about HGH, during the media swirl surrounding earlier congressional hearings -- in 2005 -- on drug use in sports. Both were playing for the Houston Astros, and Pettitte asked Clemens at spring training what Clemens would say if asked by reporters about HGH use.
Clemens responded: "What are you talking about?" according to Pettitte, and that Pettitte must have misunderstood the 1999-2000 conversation.
"He said, 'My wife used it.' " Pettitte said.
"Obviously I was a little flustered," Pettitte said, "because I thought that he told me that he did."
