NEW YORK (AP/CBS4) ― Colorado Rockies reliever Matt Herges and first base coach Glenallen Hill are among the Major League Baseball professionals named in the Mitchell Report on Thursday. Pitcher Denny Neagle is among the former Rockies players who are also named in the report which links players to steroids and other performance-enhancing drugs.

Barry Bonds, already under indictment on charges of lying to a federal grand jury about steroids, Roger Clemens, Miguel Tejada, Andy Pettitte and Gary Sheffield also showed up in baseball's most infamous lineup since the Black Sox scandal.

The report culminated a 20-month investigation by former Senate Majority Leader George Mitchell, hired by commissioner Bud Selig to examine the Steroids Era.

"Everyone involved in baseball over the past two decades - commissioners, club officials, the players' association and players - shares to some extent the responsibility for the steroids era," Mitchell said. "There was a collective failure to recognize the problem as it emerged and to deal with it early on."

Clemens was singled out in eight pages, with much of the information on the seven-time Cy Young Award winner coming from former major league strength coach Brian McNamee.

"According to McNamee, from the time that McNamee injected Clemens with Winstrol through the end of the 1998 season, Clemens' performance showed remarkable improvement," the report said. "During this period of improved performance, Clemens told McNamee that the steroids 'had a pretty good effect' on him."

McNamee also told investigators that "during the middle of the 2000 season, Clemens made it clear that he was ready to use steroids again. During the latter part of the regular season, McNamee injected Clemens in the buttocks four to six times with testosterone from a bottle labeled either Sustanon 250 or Deca-Durabolin."

Mitchell urged Selig to hold off on punishing players in the report "except in those cases where he determines that the conduct is so serious that discipline is necessary to maintain the integrity of the game."

Several stars named in the report could pay the price in

Cooperstown, much the way Mark McGwire was kept out of the Hall of Fame this year merely because of steroids suspicion.

"Former commissioner Fay Vincent told me that the problem of performance-enhancing substances may be the most serious challenge that baseball has faced since the 1919 Black Sox scandal," Mitchell said in the 409-page report.

"The illegal use of anabolic steroids and similar substances, in Vincent's view, is 'cheating of the worst sort.' He believes that it is imperative for Major League Baseball to 'capture the moral high ground' on the issue and, by words and deeds, make it clear that baseball will not tolerate the use of steroids and other performance-enhancing drugs."

Eric Gagne, Troy Glaus, Gary Matthews Jr., Brian Roberts, Paul Lo Duca, Rick Ankiel and Jay Gibbons were among other current players named in the report. Some were linked to Human Growth Hormone, others to steroids.

"We identify some of the players who were caught up in this drive to gain a competitive advantage," the report said. "Other investigations will no doubt turn up more names and fill in more details, but that is unlikely to significantly alter the description of baseball's `steroids era' as set forth in this report."
