More significant changes to Major League Baseball’s performance-enhancing drug policy were announced today by MLB and the union, and for the most part they confirmed what numerous media outlets already have reported: the program will have an independent administrator, will conduct significantly more tests each year, and will issue an annual report on the results of the testing.

Of particular interest to Baseball America readers, however, is a new provision that says MLB’s testing program will expand to include the top 200 prospects in the draft each year. MLB will notify each club about which players test positive, though those players will remain eligible for the draft. Players who refuse to take the test, however, will not be eligible for the draft.

Employers obviously have the right to test prospective employees, but this provision creates more questions than answers at this point. Who will determine the top 200 prospects? (We recommend Baseball America’s list.) When will the test be administered? And what exactly happens to the players who become ineligible for the draft because they decline to be tested? Somewhere we know Scott Boras has lawyers working on that very question. We’ll do the same and report the details and implications as we get them.
