ATLANTA — The Braves announced Monday they are leaving Turner Field and moving into a new 42,000-seat, $672 million stadium about 10 miles from downtown Atlanta in 2017. It's not clear how much it will cost taxpayers. Braves executives John Schuerholz, Mike Plant and Derek Schiller said the team decided not to seek another lease at 17-year-old Turner Field and began talks with the Cobb Marietta Coliseum and Exhibit Hall Authority in July.
