A former New York Yankee strength trainer says information he provided to the George Mitchell investigation regarding supplying Roger Clemens with steroids is included in the Mitchell report scheduled to be released later today, a source close to the trainer told ESPN The Magazine's Shaun Assael. Brian McNamee, who worked for the Yankees and as a personal trainer for Clemens and Yankee teammates Andy Pettitte, also told investigators that on at least one occasion, Clemens was in possession of steroids from another supplier, the source said. The source said McNamee told investigators he supplied Clemens with steroids while Clemens was witih the Yankees, and prior to Clemens joining the team. Also, The Bergen (N.J.) Record, citing a baseball industry official, says "several" prominent Yankees will be named in the Mitchell report. The paper said the source spoke to a third party who had seen the final report. "It's going to be a rough day in the Bronx," the paper quoted the source as saying.
