Roger Clemens' lawyer went through the syringes and medical waste from a Miller Lite can item by item trying to cast doubt on whether they were used to inject the famous pitcher with performance-enhancing drugs.
Attorney Rusty Hardin expressed shock when Clemens' chief accuser, Brian McNamee, acknowledged that some of the items in the can had been used to inject other players.
McNamee, Clemens' longtime strength coach, had testified he collected the materials after injecting Clemens with steroids.
McNamee endured a fifth day of questioning in the perjury trial of the 11-time All-Star pitcher.
Clemens is charged with lying to Congress in 2008 when he said he never used performance-enhancing drugs.
