WASHINGTON - Brian McNamee has conceded that the first time Roger Clemens asked for help with a "booty shot," the pitcher did not specifically use the word "steroids."

Under cross-examination from Clemens' lawyer, McNamee said that he assumed Clemens was referring to steroids when asking for the shot while pitching for the Toronto Blue Jays in 1998. McNamee said he was under the impression Clemens was already doing steroids.

Clemens lawyer Rusty Hardin challenged why McNamee thought that. McNamee responded that he had no physical evidence, but he referenced a conversation he overheard Clemens have with another player, Jose Canseco, but could not provide specifics.

Clemens' request for help came less than a month before the date on which McNamee says he gave Clemens his first injection.
