Tempe, Ariz. ? Commissioner Bud Selig hopes major league baseball can institute a zero-tolerance policy on steroid use similar to one that covers players with minor-league contracts.

Selig recently sent a directive to all 30 teams, telling them to decline comment on steroids and the federal grand jury that indicted Barry Bonds’ trainer.

“There’s been enough comment,” he said. “We know what we have to do and we’re going to do it.”

Selig, attending Anaheim’s game against San Diego, sought to put baseball’s focus back on the field. He spent several minutes fending off steroid-related questions.
