PARADISE VALLEY, Ariz. – Major League Baseball will test for human growth hormone throughout the regular season and increase efforts to detect abnormal levels of testosterone, a decision the NFL used to pressure its players.

Baseball players were subject to blood testing for HGH during spring training last year, and Thursday’s agreement between management and the Major League Baseball Players Association expands that throughout the season. Those are in addition to urine tests for other performance-enhancing drugs.

Under the changes to baseball’s drug agreement, the World Anti-Doping Agency laboratory in Laval, Quebec, will keep records of each player, including his baseline ratio of testosterone to epitestosterone, and will conduct carbon isotope ratio mass spectrometry (IRMS) tests of any urine specimens that “vary materially.”
