Segui could be reluctant witness against Clemens updated 3:29 p.m. WASHINGTON (AP) - Former major leaguer David Segui (seh-GEE') is on the verge of having to testify in the Roger Clemens perjury trial, even though he doesn't want to. Prosecutors want Segui to relate a conservation he had with Clemens' former strength coach, Brian McNamee, in 2001. McNamee supposedly talked to Segui about saving waste from injecting players in order to placate McNamee's wife. That would be consistent with McNamee's testimony as to when and why he saved evidence after allegedly injecting Clemens with steroids that year. U.S. District Judge Reggie Walton will rule Thursday whether Segui has to testify. When told Segui doesn't want to, the judge said: "If he doesn't show up, he'll be arrested like anyone else." Clemens is accused of lying to Congress when he denied using performance-enhancing substances.
