PHOENIX -- Arizona Diamondbacks manager Chip Hale walked out to the mound in the eighth inning, fully ready to bring in closer Brad Ziegler.

Before pulling the trigger, he wanted to visit Rubby De La Rosa to determine if he had anything left.

Seeing and hearing what he wanted from his starter and catcher Welington Castillo, Hale left De La Rosa in and the young right-hander got two big outs.

De La Rosa pitched eighth effective innings and Ziegler held on for his 14th straight save, lifting the Diamondbacks to a 2-0 victory over the Milwaukee Brewers on Saturday night.

"As I was walking out there, I wanted to look into his eyes and see what I saw and also talk to Castillo," Hale said. "Both of them were very positive, felt very good about getting the outs they needed so I just tapped him on the chest and said you got it."

Paul Goldschmidt and Jake Lamb both had run-scoring hits in the first inning against Taylor Jungmann (5-2) for the Diamondbacks, who had four hits -- two after the opening frame.

That ended up being enough for De La Rosa (8-5), who gave Arizona its third straight quality start.

Effectively working the ball down in the zone, De La Rosa allowed four hits and struck out six to follow up strong performances by Zack Godley and Patrick Corbin. The three combined to allow one earned run with 23 strikeouts in 21 innings.

"We always talk about things are contagious, hitting, pitching and it seems like when one guy has a good outing, the next guy wants to do better and keep it going," Hale said.

Milwaukee put up a late fight after being limited to four hits the first eight innings.

The Brewers loaded the bases in the ninth after Ziegler gave up two two-out singles and walked a batter, but Arizona's closer struck out Gerardo Parra for his 16th save in 17 chances.

It was Arizona's first shutout since beating the San Francisco Giants 4-0 on June 14, and sixth of the season.

"He threw a nice backdoor slider to Gerardo," Brewers manager Craig Counsell said. "We gave ourselves a chance."

De La Rosa has been sterling at home, going 5-1 at Chase Field to match the NL's best home winning percentage.

He was sharp again, working around traffic in nearly every inning.

Lamb gave De La Rosa a defensive boost in the fourth inning, diving to snare a ball to his left, jumping up and throwing out Carlos Gomez at first. De La Rosa also overcame errors by Lamb and shortstop Cliff Pennington in the fifth inning.

Hale visited De La Rosa after a one-out walk in the eighth inning, but left him in to the cheers of large home crowd there, in part, to celebrate Randy Johnson's induction into the Hall of Fame. De La Rosa got Ryan Braun to line out to center, then Shane Peterson on a groundout before Ziegler took over in the ninth.

"I feel good in that inning and I want to get these guys, I want to finish my innings and he had confidence in me," said De La Rosa, who is 10-0 with a 1.15 ERA in his last 14 starts when throwing seven or more innings.

Jungmann has pitched well since being called up from Triple-A Colorado Springs on June 9, allowing more than two earned runs once in eight starts.

The Diamondbacks had two against the big right-hander in the first inning, on Goldschmidt's 151st career double -- moving him past Steve Finley for fifth on Arizona's all-time list -- and Lamb's single.

Jungmann shut down the Diamondbacks after that, working around four walks and four hits in six innings. He struck out seven.

"I'm happy with the adjustment I made. I'm not happy with the entire outing because the first inning was a little frustrating," Jungmann said. "It was just a frustrating outing."
