Some of the Yankees? biggest stars have been named in the long-awaited report on steroids in Major League Baseball, compiled by former Senator George Mitchell.

Roger Clemens and Yankees? left-handed pitcher Andy Pettitte were among the first names to emerge from the 409-page Mitchell report. Clemens, a seven-time Cy Young winner, was singled out in Mitchell?s report on nearly nine pages.

Most of the information on Clemens came from Brian McNamee, a former strength and conditioning coach for the Yankees. McNamee claimed he injected Clemens with steroids throughout the 1998 season and again throughout the 2000 season. He also said he injected Pettitte during the 2002 campaign.

The investigation took Mitchell 20 months to complete, and contained more than a dozen names of former and current Yankees, including Ron Villone, Kevin Brown, Chuck Knoblauch, Glenallen Hill, Mike Stanton, Rondell White and David Justice. Former Mets catcher Paul Lo Duca is also named in the report.

Other players Mitchell said got caught up in the drive to gain a competitive edge are Barry Bonds, Miguel Tejada, Jason Giambi and Gary Sheffield. Bonds is already under indictment on charges of lying to a federal grand jury about steroids.

Mitchell said the investigation led him to find that there has been a widespread use of illegal steroids, hormones or performance-enhancing substances in the sport, and that Major League Baseball has been slow to react. According to the report, every Major League Baseball club had players test positive for one of the drugs.

It is uncertain if any penalties or suspensions will come, but Mitchell urged Major League Baseball commissioner Bud Selig to hold off on punishing the players named, except in cases so serious that discipline is necessary to maintain the integrity of the game.
