Jason Kubel had a two-run double in the sixth to tie the score for the Diamondbacks.
Trevor Bauer, the No. 3 overall draft pick in 2011, did not receive a decision in his major-league debut for Arizona after he was called up from Triple-A Reno earlier in the day.
David Hernandez (1-0) earned the win with a scoreless eighth, allowing no hits, walking two and striking out the side.
J.J. Putz earned his 14th save in 17 chances, retiring Michael Bourn on a groundout, striking out Jason Heyward and getting Martin Prado to ground out.
The Diamondbacks have won five of seven and 15 of 23. They snapped a season-high four-game losing streak on the road.
Kimbrel (0-1) allowed just one hit – the first homer he’s allowed this season – and struck out one.
The Braves, who have lost three of five, left 21 runners on base.
Brian McCann had an RBI double in the third inning and Bourn made it 2-0 with a sacrifice fly in the fourth.
Young homered for the second night in a row, but was batting .151 in his previous 106 at-bats and had been dropped to eighth in the batting order. Arizona has homered in nine consecutive games for the first time since July 20-Aug. 1, 2010.
Bauer allowed five hits, two runs, three walks and struck out three in four innings. The 21-year-old right-hander, who left for a pinch-hitter in the fifth, threw 42 of his 74 pitches for strikes.
Braves starter Jair Jurrjens couldn’t hold a 2-0 lead in the sixth.
Kubel, who began the night leading the NL with 24 RBI in June, made it 2-2 in the sixth with a double that scored Willie Bloomquist from second and Justin Upton from first.
A wild pitch walk to Miguel Montero moved Kubel to third and chased Jurrjens, who allowed six hits, two runs and three walks with no strikeouts in 5 2-3 innings.
Kris Medlen and Eric O’Flaherty combined to hold the Diamondbacks scoreless in the seventh and eighth.
Jurrjens was making his second start since getting recalled from a demotion to Triple-A Richmond and winning 4-1 at Boston last Friday.
