Veteran baseball executive John Hart, a former Orioles coach and minor league manager, has reversed course and accepted a three-year deal to become president of baseball operations with the Atlanta Braves, taking over Frank Wren's position after Wren, a former Orioles general manager, was fired Sept. 22. Hart, 66, who has been acting as interim general manager, said earlier this month that he preferred to remain with the team as its top adviser rather than committing to a job with such significant time demands. Hart was the first choice of Atlanta president John Schuerholz and Bobby Cox, the Braves' former manager now serving in a top adviser role, who first tried to persuade Hart to take the job after the firing of wren. Hart joined the Braves in November 2013. A two-time Major League Executive of the Year, he spent 2002-2005 as GM and 2006-2013 as senior adviser for the Texas Rangers. He spent 13 seasons with the Cleveland Indians, the last 10 as executive vice president and general manager.
