Here’s what Major League Baseball commissioner Bud Selig should do: inform Roger Clemens and the other players on George Mitchell’s list that if they do not come clean about their usage of performance-enhancing substances, they will not be eligible for induction into the National Baseball Hall of Fame. The players, to this point, have refused to cooperate with investigators. Selig has leverage; he should use it. If Pete Rose can be kept out of the Hall for wagering on baseball, Clemens and others can be kept out of the Hall for cheating. Don’t say they haven’t been convicted of cheating. Rose wasn’t convicted of wagering on baseball. This has nothing to do with criminal justice; it has everything to do with the integrity of the sport. It’s the job of the commissioner to preserve, protect, and promote the integrity of the sport.
