ATLANTA — The Atlanta Braves have optioned right-handed pitcher Brandon Cunniff to Triple-A Gwinnett and added outfielder Joe Benson to the list of non-roster invitees with two days remaining in spring training. The 27-year-old Benson signed with the Braves as a minor-league free agent in January. He is hitting .250 with one homer — off Philadelphia's Cole Hamels on Wednesday — and two RBIs in nine spring training games in his surprising bid for a bench spot.
