Van Slyke's home run followed two-out singles by Adrian Gonzalez and Howie Kendrick after the Dodgers had wasted three earlier scoring opportunities while falling behind on a second-inning homer by Rickie Weeks Jr., who also doubled. Arizona cut the lead in half in the bottom of the sixth on a leadoff single by Michael Bourn and a rocket RBI single off the top of the left-field wall by Paul Goldschmidt.
Joe Blanton got two outs in the eighth and Jansen pitched the ninth for his 19th save and 161st of his career, tying Eric Gagne for the franchise record.
