Pitching coach Leo Mazzone and the Baltimore Orioles reached agreement on a three-year contract Wednesday night, hours after the Atlanta Braves coach ended discussions with the New York Yankees. ``The deal is finished business,'' according to a source close to the negotiations, who spoke to The Associated Press on the condition of anonymity. Mazzone, considered to be one of the finest pitching coaches in the majors, has been in the Atlanta organization since 1979 and was pitching coach of the Braves since 1990. He will replace Ray Miller, who served as pitching coach of the Orioles since June 26, 2004. Orioles executive vice president Mike Flanagan declined comment, and Baltimore manager Sam Perlozzo, a longtime friend of Mazzone, did not return a phone call from The Associated Press.
