WASHINGTON — It took 24 witnesses over 19 days of testimony for prosecutors to make their case against Roger Clemens, with three jurors and two minor pieces of the indictment dismissed by the time they were done. With the overlong-running trial now in its seventh week and Clemens' lawyers starting to take their turn, the case remains centered on the credibility of one person — Brian McNamee.

WASHINGTON — It took 24 witnesses over 19 days of testimony for prosecutors to make their case against Roger Clemens, with three jurors and two minor pieces of the indictment dismissed by the time they were done. With the overlong-running trial now in its seventh week and Clemens' lawyers starting to take their turn, the case remains centered on the credibility of one person — Brian McNamee.

The government rested Tuesday in the perjury trial of the seven-time Cy Young Award winner, wrapping up with a witness from Wall Street and two from the FBI. Two invoked the name of McNamee, the longtime Clemens strength coach who says he injected the ex-pitcher with steroids in 1998, 2000 and 2001 and with human growth hormone in 2000.

The defense is expected to take about two weeks to call its witnesses. The trial has already exceeded the original estimate of four to six weeks stated by the judge at the start.
