Lock it up sluggers, there's a new sheriff in town. Major League Baseball and the players' association reached an agreement to expand the sport's drug program, including random in-season blood testing for human growth hormone and a new test to catch players using testosterone. The move puts the baseball world on an elevated playing field in comparison with the NFL, which has yet to enforce tests for either HGH or testosterone. It’s the first step in commissioner Bud Selig's plan to turn baseball into the strictest professional sport on drug use. Eight baseball players were suspended for drug use in 2012.
