Toronto Blue Jays pitcher Roger Clemens (bottom) stretches with the help of team strength and conditioning coach Brian McNamee before the start of a spring training game against the Cincinnati Reds in Sarasota, Florida, in this March 2, 1998 file photo. The Mitchell Report, released December 13, 2007, names Clemens as one of the players who used performance-enhancing substances during his career. McNamee, who was Clemens' strength and conditioning coach while he was a player with both the Toronto Blue Jays and New York Yankees, spoke to former U.S. Senator George Mitchell as part of a deal with the U.S. Attorney's office.
