NEW YORK — Major League Baseball implemented random blood testing for human growth hormone in the minor leagues, the first professional sports league in the United States to take the aggressive step against doping.

The blood testing becomes part of the Minor League Drug Prevention and Treatment Program, which Commissioner Bud Selig introduced in 2001 to test for performance-enhancing drugs.

Testing will be limited to minor league players because they are not members of the players' association, which means that blood testing is not subject to collective bargaining.

CORAL GABLES, Fla. — Miami and Notre Dame agreed to renew a football rivalry that during the 1980s helped define each program and decide several national championships.The Hurricanes and Fighting Irish will play Oct. 6, 2012, at Soldier Field in Chicago, then play a home-and-home starting in 2016 at South Bend, Ind. They play in Miami the next season.
