Ian Kennedy earned his 14th victory of the season after giving up three earned runs over seven innings of work. Clayton Kershaw went 6.1 innings and picked up a rare loss, dropping to 13-5 in 2011.
Kennedy was solid but gave up six hits, including a home run to Matt Kemp and an RBI double to Andre Ethier.
The Diamondbacks jumped all over Kershaw in the first inning, scoring two runs on a Kelly Johnson home run. After that, Kershaw was untouchable -- until the seventh inning.
With one out in the seventh, Collin Cowgill roped a line drive single to left field. Cody Ransom, spot starting in place of Willie Bloomquist, stepped into the batter's box and hit a mammoth home run to left field, causing Kershaw to jump up and down in disgust and pushing D-backs fans into celebration.
David Hernandez and J.J. Putz were perfect in relief, pitching two innings and shutting the door on the Dodgers.
This win was crucial for the Diamondbacks, who had lost three in a row and were scuffling at the absolute worst time. The San Francisco Giants remain a half game ahead of the D-backs in the NL West standings after defeating the Philadelphia Phillies on Sunday afternoon.
Next on the schedule: Arizona takes on the Houston Astros in a three game series that starts Monday night at 6:40 PM. The D-backs are running a promotion where kids get a free ticket when an adult ticket is purchased for all three games in the Astros series.
