WASHINGTON — After spending the morning in the House hearing into steroid use in Major League baseball, I have a modest suggestion.

Call it the “Mister Universe” test. If an athlete who used to have a normal body develops a physique reminiscent of Arnold Schwarzenegger in his prime, that should be enough to justify an investigation—or at least a pop urine test—of that player.

When Barry Bonds and Mark McGuire grew from normal proportions into Superman look-alikes, most observers concluded they were cheating in some fashion. Yet that apparently was not enough to trigger an investigation.

Just this week, the baseball league created a new investigations unit staffed by veteran law enforcement officials and authorized to check out all allegations of drug use (including anonymous tips to a new hot line). The investigators should also be authorized to look into evidence in plain sight—such as an athlete who somehow develops into an Adonis, and seems headed for the Hall of Fame.
