Sport News : Ex-MLB player David Segui can testify in Clemens trial: judge

According to prosecutors he has been reluctant to travel to Washington for the trial without knowing he will definitely testify.

Federal prosecutors had filed a motion to bring Segui as a witness in order to question him about a conversation between Segui and Clemens' former personal trainer Brian McNamee, who has said he injected Clemens with steroids and human growth hormone.

McNamee allegedly told Segui about having saved needles used to inject players with steroids or human growth hormone.

Anthony Corso will a lso be allowed to be called by the government, U.S. District Judge Reggie Walton ruled. Corso was one of McNamee's clients in New York and could testify that McNamee told Corso that Clemens had used human growth hormone and that McNamee had saved evidence from 2001.

Both testimonies would bolster the claims of McNamee, the core of the government's case against the seven-time CY Young Award winner.

Clemens, 49, is being tried for a second time on federal charges of lying in 2008 to the U.S. House of Representatives' Committee on Oversight and Government Reform, which was investigating drug use in Major League Baseball. His first trial ended in a mistrial last year.

Clemens, a seven-time Cy Young Award winner as best pitcher, has repeatedly denied taking performance-enhancing drugs or lying to lawmakers, saying that McNamee had injected him with shots of vitamin B12 a nd the anesthetic lidocaine instead.
