MILWAUKEE, July 6 (UPI) -- Gerardo Parra drove in three runs, backing seven strong innings from Zach Duke in the Arizona Diamondbacks' 7-3 win over Milwaukee Tuesday.
Parra's RBI single in the first inning capped a four-run Diamondbacks uprising and he added a solo homer in the third, extending Arizona's lead to 7-1.
Justin Upton added two hits, including a bases-empty home run, and Miguel Montero drove in a pair for the Diamondbacks, who clinched their three-game series and picked up their third win in four games.
Duke (2-3) earned his first career win in Milwaukee after going 0-6 there previously, holding the Brewers to two runs on five hits, issuing a pair of walks and fanning one.
Randy Wolf (6-6) was tagged with the loss, surrendering seven runs on 10 hits before leaving after six innings.
Prince Fielder belted his 22nd homer and added a run-scoring single for the Brewers, who played their third straight game without injured all-star outfielder Ryan Braun (strained calf).
Milwaukee lost for the seventh time in eight games and fell into third place in the National League Central, two games behind the first-place St. Louis Cardinals.
