PHOENIX -- Tony Campana was the unlikely hero and Brad Ziegler gained a measure of redemption, even if he didn't look at it that way.
The light-hitting Campana singled home Martin Prado from third base with two outs in the ninth inning to give the Arizona Diamondbacks a 4-3 victory over the Milwaukee Brewers on Wednesday night.
Ziegler (3-1), who gave up the deciding grand slam in Tuesday night's 7-5 Milwaukee victory, retired all four batters he faced, three by strikeout, to get the victory.
In the ninth, Prado doubled with one out to deep left center off Brandon Kintzler (1-3), advanced to third on David Peralta's groundout, then scored when Campana slapped one up the middle.
Campana's first career walk-off hit raised his batting average to a whopping .150.
"It was cool. I don't think I've ever done it in the minor leagues, either," he said. "If I'm here, I'm happy."
Campana made the big league club out of spring training but, after going 1 for 30 at the plate, was sent down to Triple-A Reno on May 1. He was called back up last Friday.
Campana may not hit well but he is fast.
"Actually it couldn't have worked out better to have him up there," Arizona manager Kirk Gibson said, "just because we had a guy on third base and just his wheels, it can pressure them, makes them come in and cheat in. He put the bat on the ball."
Ziegler said he wasn't thinking about retribution when he came out of the bullpen.
"I don't know what the TV broadcasters got going. They're probably bringing up yesterday a lot," he said, "but we're not. We're just watching the game flow. With nine righties in the (Brewers') lineup, I knew there was a good chance I'd pitch."
Khris Davis hit a three-run homer for the Brewers' runs.
Arizona's Chris Owings, hit below the back of the head by a pitch from Kyle Lohse on Tuesday night, was a home run shy of the cycle. He was robbed of a fourth hit by a diving stop by first baseman Mark Reynolds.
Jonathan Lucroy's grand slam on Tuesday came one pitch after reliever Evan Marshall hit Ryan Braun with a pitch and was ejected. Wednesday's game had no such drama.
"We didn't do a lot offensively," Brewers manager Ron Roenicke said. "We just had the one inning with Davis hitting a three-run homer. Besides that, we didn't swing the bats very well"
Starters Wade Miley of Arizona and Matt Garza of Milwaukee left without a decision after 7-2/3 innings. Miley gave up three runs and five hits, striking out eight with no walks. Garza allowed three runs -- two earned -- and seven hits. He struck out four without a walk.
Miley retired 10 straight, striking out Ricky Weeks and Braun to start the eighth, but walked Lucroy and Carlos Gomez. That ended Miley's night. Ziegler came in and fanned Aramis Ramirez.
Garza retired 15 of 16 before Owings' one-out double in the eighth. Paul Goldschmidt's groundout moved Owings to third, but Brewers setup man Will Smith came on to strike out Miguel Montero and end the threat.
Miley had fanned four straight when Lucroy led off the fourth with a single. Gomez, back after sitting out two games with a sore hamstring, moved Lucroy to third with a single, extending his hitting streak to 14 games, matching his career-best.
Arizona got two in the Brewers' sloppy first inning, one unearned.
Gerardo Parra tripled down the right field line, then Owings singled him home. Goldschmidt followed with a grounder to the second baseman Weeks, whose errant soft toss to shortstop Jean Segura covering second left both runners safe. Montero followed with a grounder to short for what looked to be an inning-ending double play. Segura threw to Weeks for the force at second, but the throw to first bounced in the dirt and the runner was safe, allowing the second run to score.
In the third, Owings tripled off the center field wall and scored when Goldschmidt singled for his 52nd RBI.
The Diamondbacks will try to salvage a split of the four-game series Thursday.
It was evident early the D-backs saw something they could use to run on Brewers right-hander Matt Garza. Garza had given up only one stole base this season but the D-backs had two by the third inning. David Peralta stole second base in the second and Paul Goldschmidt stole second in the third. Both did so relatively easily.
23 -- road victories by Milwaukee, most in the majors
* Tony Campana's game-winning single was the first walk-off hit of his four-year career, and it snapped a streak in which he had one hit in his previous 39 at-bats. It was his first hit since being recalled from Reno last Friday. "If I'm here, I'm happy," Campana said. "Just got a ball on the ground and snuck it through."
* Wade Miley's tough luck continued. Miley gave up three runs on five hits and four walks in 7-2/3 innings while striking out eight. But he did not figure in the decision. The only damage was Khris Davis' three-run homer in the fourth that tied the game at 3. "Even the Davis home run, I felt like I made a pretty good pitch," Miley said. "Just have to be a little bit smarter in that situation." Davis hit a breaking ball that was on the inside corner at the knees, a well-located pitch. Miley has won only one of his last 13 starts, but he has made seven quality starts in that span."
* Brad Ziegler saw how aggressive the Brewers hitters were with runners in scoring position in their 7-5 victory Tuesday, and he pitched accordingly while striking out Aramis Ramirez with two on and two in the eighth inning. He got the biggest out of the game with sliders and changeups. "He's been a great fastball hitter his whole career, so you just have to pitch cautiously, especially with runners in scoring position, because he is going to be ultra-aggressive," Ziegler said. "I had a pretty good feel for my off-speed stuff, so I decided to stick with it."
* Chris Owings was a home run short of the cycle the day after taking a fastball in the upper back that left a welt still visible Wednesday. Owings bore no ill will toward Kyle Lohse, who hit him in the sixth inning. Lohse nodded toward Owings in a gesture of apology as the two left the field following the inning. "There is no bad blood there," Owings said.
The advantage of a left-handed specialist -- Brewers' lefty Will Smith has retired seven of the eight batters he has faced while appearing in the first three games of the series -- can be great. Smith struck out Miguel Montero with the go-ahead run on second base in the eighth Wednesday and has struck out Montero three times in the series. D-backs' lefties are 0-for-4 against Smith this series.
