Major League Baseball on Tuesday took a stand against admitted steroids user Jose Canseco, calling the former slugger's allegations that the league might be playing favorites with some big-name players when it comes to positive drug tests "complete nonsense." Canseco, who last played in the majors for the White Sox in 2001, returned to professional baseball with the San Diego Surf Dawgs on Monday. Before the game, he made critical comments about how baseball officials are handling the new, stricter steroids policy and said a "cleanup" in the commissioner's office is needed.
