Major League Baseball has announced it will begin testing for human growth hormone during the 2013 regular season.

“This agreement addresses critical drug issues and symbolizes Major League Baseball’s continued vigilance against synthetic human growth hormone, testosterone and other performance-enhancing substances,” MLB Commissioner Bud Selig said in a statement.

The announcement of the random testing comes one day after baseball writers balked at naming any new players to the Hall of Fame.

Barry Bonds, Sammy Sosa and Roger Clemens were among those eligible, but their career achievements have been clouded by alleged use of performance-enhancing drugs.
