NEW YORK -

Major League Baseball's key witness in its case against Alex Rodriguez says he designed and administered an elaborate doping program for the 14-time All-Star that started in 2010.

Anthony Bosch, the owner of the now shuttered Florida anti-aging clinic, Biogensis, said in an interview on "60 Minutes" Sunday night Rodriguez paid him $12,000 per month to provide him with an assortment of banned drugs that included testosterone and human growth hormone.

Rodriguez's suspension was reduced Saturday by an arbitrator from 211 games to 162, plus all playoff games next season.

MLB Chief Operating Officer Rob Manfred said in the segment Bosch agreed to cooperate with the investigation because he felt his life was in danger.

The players' association said in a statement it is disappointed MLB participated in the show and is considering its legal options.
