In an effort to move beyond the era of steroid abuse, Major League Baseball announced a revised drug testing agreement calling for an additional 600 drug tests during the baseball season, USA Today reported April 11.

The agreement also includes an increase in offseason testing, and mandates drug-testing of the top 200 amateur draft prospects. The list of banned substances will be expanded to include insulin-like growth factor (IGF-1), gonadotropins, aromatase inhibitors, selective estrogen receptor modulators and anti-estrogens.

"Baseball already has the toughest penalties in professional sports and our testing program will now be more rigorous and independent than ever, with additional in-season and offseason tests," said baseball commissioner Bud Selig. "I will continue to take every step necessary to protect the integrity of this game."

Dr. Bryan Smith, the drug-testing program's independent administrator, will have more independence as a result of the revised agreement. The Treatment Board, a joint effort by management and the players union, will supervise drugs of abuse like cocaine.

Player suspensions that resulted from the release of Sen. George Mitchell's report on steroid abuse in baseball were eliminated and the players named will instead be required to participate in community service activities.

The Players Association will make a $200,000 contribution to anti-drug and research organizations, and teams named and fined in the Mitchell Report will donate money to the Partnership of a Drug Free America and the Taylor Hooton Foundation.
