WASHINGTON (AP) — The judge in the Roger Clemens perjury trial, which begins Wednesday, is considering just how much of a salacious allegation against the star pitcher’s chief accuser is fair game, and he’s probably not going to let a parade of Clemens’ former New York Yankee teammates testify about their drug use.

U.S. District Judge Reggie Walton held a pretrial hearing Tuesday to consider what jurors will learn about trainer Brian McNamee, who has said he injected Clemens with steroids and human growth hormone several times during the decade they worked out together. Clemens’ defense is focused on convincing jurors that McNamee is a liar, and his attorneys also want to introduce allegations that McNamee drugged and raped a woman in a Florida hotel pool while on a trip with the Yankees in 2001.

McNamee was questioned by local police and admits misleading them, but he has never been charged and has said he was trying to rescue the woman from drowning. Walton said he’s concerned that the rape allegation would be “extremely prejudicial,” but Clemens’ attorneys say it shows why McNamee would have a motive to fabricate evidence that he injected their client with illegal drugs.

The investigation occurred in 2001, the same year that Clemens helped lead the Yankees to a World Series championship and that McNamee says he decided to save needles and gauze that he used to inject the star pitcher.

McNamee’s Yankee contract was not renewed after the Florida investigation. Clemens attorney Rusty Hardin said those events in 2001 prompted McNamee to begin fabricating evidence against Clemens to protect himself financially.
