ATLANTA — The Braves traded Tommy Hanson to the Los Angeles Angels for former closer Jordan Walden on Friday, clearing a spot in the Atlanta rotation for Julio Teheran, Randal Delgado or another young starter. Hanson has seen a decrease in his velocity as he battled rotator cuff tendinitis in 2011 and a lower back strain in 2012. Angels general manager Jerry Dipoto said the 26-year-old was a consistent winner in four seasons with the Braves and had no arm troubles this year.
