Bud Selig insisted the sport's current drug-testing program was working, but the baseball commissioner also said he proposed even tougher rules last month in order to end suspicion. ``Just the impugning of one's integrity and the sport's integrity is something that we just can't allow,'' Selig said Wednesday after owners unanimously endorsed his plan. ``Is it unfair? Yeah, I believe it is unfair, but we have to do something about it so we quit talking about it.'' Selig's steroids proposal, made to the union last month, calls for a 50-game ban for first-time offenders, a 100-game penalty for second-time offenders and a lifetime ban for a third positive test. It also would penalize the use of amphetamines and have an outside expert run the program. ``This became fairly or unfairly an integrity issue, an integrity issue of everybody in the sport, starting with the commissioner. And that, frankly, is what has driven me,'' Selig said. ``Whether the program is working today is not the issue because I think we would agree with the players' association it is working. That isn't the issue because the integrity issue transcends that.''
