Major League Baseball [PDF ebook] 

Baseball players have always looked for "pick-me-ups" to make it through the long season. In the late 1980s, however, some players began using banned and illegal performance-enhancing drugs. Starting with slugger Mark Mc Gwire and then continuing with Barry Bonds and Roger Clemens, many of today’s best players have been accused of cheating their way into the record books. This book discusses the history of baseball and performance-enhancing drugs and takes a closer look at the lives ruined and the reputations sullied.
