Major League Baseball union chief Michael Weiner says that it is premature to discuss the possibility of HGH testing. "We don't know enough about that (procedure) yet. We just had our first meeting today. We will probably talk about that as we go on," Weiner said Friday. Major league baseball issued a statement Wednesday that said it is considering immediate steps to implement HGH testing in the minor leagues, and that commissioner Bud Selig is committed to dealing with the issue at the major league level.
