Rich Hartmann sits in a booth at a Penn Station restaurant and sips on a beer as he waits with dozens of other commuters for the train home to Long Island and wonders what might have been. Hartmann is now a 35-year-old operations manager at a Manhattan bank, but in the mid-1990s he was a minor league pitcher in the St. Louis Cardinals' organization. He doesn't know if he was good enough to play in the big leagues. But he suspects he never got a fair shot, and he's certain there were many minor leaguers who were denied a chance at Major League Baseball because they refused to use steroids. "Was I cheated of my dreams of a big-league career?" Hartmann asks. "I don't know. But I do know there were thousands of guys who were right on the doorstep between 1990 and 2005, and they were cheated because they didn't use steroids."
