Mark McGwire and Jose Canseco--the Bash Brothers--ushered in a new era of muscle-bound power hitters in baseball in the late 1980s. Suddenly balls were flying out of the parks like never before, and the rest of baseball stood up, took notice, and followed suit. Baseball's bodybuilding revolution, with its resultant steroid infestation, was here to stay, and many experts today point to these two players as a large reason why. Author Dale Tafoya has interviewed more than 150 teammates, coaches, scouts, and friends who knew McGwire and Canseco during that era, including former A's general manager Sandy Alderson, former team president Roy Eisenhardt, former commissioner Fay Vincent, Hall-of-Fame closer Dennis Eckersley, and 2004 Ford C. Frick award-winning legendary broadcaster Lon Simmons. They provide first-person commentary on what living and playing with the larger-than-life duo was like, and relate the shock and awe that followed both players and the team as well. Tafoya also investigates the players' pre-Oakland careers, how they exploded upon reaching the majors with the A's, and what happened when the two moved on. While Canseco has admitted his steroid use, McGwire ducked the question when Congress asked about his use by saying, "I am not here to discuss the past." Tafoya investigates the claims of each. The Bash Brothers revolutionized baseball; Tafoya discusses whether it was for better or for worse and paints a colorful portrait of the duo's rise to popularity and their ensuing exposure and shame. "Bash Brothers: A Legacy Subpoenaed" is the first book to fully investigate how these two players helped shape baseball for years to come.
