ATLANTA — Jason Heyward moved into THE locker on Sunday — the spot in the Atlanta Braves clubhouse used by Chipper Jones. Another confirmation of a new era in Atlanta comes Monday night, when Jones throws out the ceremonial first pitch before the Braves open their season against Cole Hamels and the Philadelphia Phillies. While Jones has retired, expectations are high in Atlanta after the Braves added brothers Justin and B.J. Upton to join Heyward in the outfield.
