Commissioner Bud Selig defended baseball's fight against performance-enhancing drugs on Wednesday while declining comment on the suspension of Milwaukee Brewers outfielder Ryan Braun or whether other stars will also face penalties.

Braun was suspended for the balance of the season on Monday for violating baseball's anti-drug policy.

Since the program was implemented in 2004, 32 major league players have been suspended for using banned substances. Three were suspended a second time.
