Jason Heyward bashed a three-run homer Saturday and the Atlanta Braves went on to break San Francisco\'s five-game winning streak with a 7-3 victory. Heyward\'s shot in the third inning staked the Braves to a 3-0 lead and Michael Bourn added a key run-scoring single in the seventh that increased Atlanta\'s advantage to 4-1. After Gregor Blanco\'s two-run double in the seventh pulled the Giants to within a run, Bourn and Martin Prado each coaxed a bases-loaded walk in the eighth against Jeremy Affeldt to ice the victory. Mike Minor (7-10) surrendered three runs on four hits over 6 2/3 frames to earn the victory, which broke a personal three-start losing streak. The left-hander didn\'t allow a walk and struck out five for the National League wild card-leading Braves. Loser San Francisco starter Madison Bumgarner (14-8) coughed up four walks and seven hits over 6 1/3 frames. Brandon Belt drove in a run for the NL West-leading Giants.
