Major League Baseball responded to the Mitchell report yesterday, issuing new security measures that will attempt to block performance-enhancing drugs from entering team clubhouses and their use by players.

The New York Daily News reported [1] five measures announced by MLB to increase clubhouse security.

• Background checks will be performed on all existing clubhouse personnel and new hires.
• Random drug tests will be performed on all clubhouse personnel.
• Clubs will be required to maintain a log of all packages sent to clubhouses at major league ballparks.
• Clubs will be required to distribute Major League Baseball's policy of "disclosing information relating to the use, possession or distribution of prohibited substances" to all club employees and to post the policy in the clubhouse.
• The overnight notice to clubs before the arrival of the Comprehensive Drug Testing personnel has been eliminated. All clubs will be required to have a single, designated area for collections in both the home and visiting clubhouses. Collectors will be provided with permanent, official credentials and their access will be facilitated.

The paper reports many of these new measures were introduced to ensure there's no way another Kirk Radomski can get access to players and sell them performance-enhancing drugs. Radomski was a New York Mets [2] clubhouse attendant who used his insider position to funnel drugs to many major league ballplayers as his "customers referred their friends and teammates to him as they moved from club to club," according to the Mitchell Report [3].

Baseball Commissioner Bud Selig also said in a statement that more changes will follow based off of the Mitchell Report's recommendatons.
