Baseball Commissioner Bud Selig is defending the league's fight against performance-enhancing drugs.

Selig was at Miller Park in Milwaukee on Wednesday for a youth event. He said he couldn't discuss the investigation surrounding the now-closed Biogenesis clinic that resulted in a season-long ban for Brewers outfielder Ryan Braun.

Selig says he is proud of what Major League Baseball has done and that aggressive drug testing will continue.
