Arizona was two strikes away from winning in the ninth when Murphy hit a 431-foot blast to right-center off Paul Sewald. It was Murphy's fifth homer of the season and also represented Sewald's third straight blown save.
Austin Riley also homered for the Braves, who won their third straight game.
Corbin Carroll had the lone run-scoring hit for the Diamondbacks, who had just four hits. Arizona missed a chance to move above .500 for the first time since April 3.
