ATLANTA -- Braves shortstop Andrelton Simmons wasted no time recovering from a rare two-error inning.
"It's a tough when your errors are a little costly, but [Aaron] Harang picked me up and kept us in the game," Simmons said. "The other guys got on base and we ended up winning, so it's a good day after all."
Justin Upton added a two-run homer and a third RBI for the Braves, who have won 11 of 12 and are 11 games over .500 for the first time this season.
Harang (8-6) has a 3.00 ERA over his last three starts after allowing nine hits and four runs with one walk and one strikeout in eight innings.
Arizona, which has dropped eight of 12, lost its 53rd game, most in the majors.
Simmons had an RBI single in the first and a two-run double in the fourth. He appeared to turn his left ankle while running the bases in the sixth but stayed in the game. He drove in his fourth run with a groundout in the seventh to make it 10-4. It marked the third time in his career and second time this season that he had four RBI in a game.
Simmons has four straight games with at least two hits.
The Diamondbacks went ahead 3-0 in the first on Paul Goldschmidt's RBI double, Montero's RBI single and Gerardo Parra's's RBI single. Parra got an at-bat after manager Kirk Gibson successfully challenged that Aaron Hill, the previous batter, was safe at first on Atlanta's double-play attempt.
"We had a rough first inning there, but nobody panicked," Harang said. "Our confidence is real high right now, and everybody's feeling good about how we're swinging the bats and playing defense. We knew guys were comfortable up there and knew that we'd stay right in it."
Simmons, named last year's Platinum Glove winner as the NL's best defender, had two errors in the first. Simmons began the game with six errors this year.
"I told him that how you bounce back from those is what's important," Braves manager Fredi Gonzalez said. "He made some great plays defensively after that inning and also swung the bat. He kept the line moving."
After Simmons cut the lead to 3-1 in the first, the Braves made it 3-2 in the third on Jason Heyward's RBI single.
Atlanta took a 7-3 lead with a five-run fourth off Mike Bolsinger (1-5).
Bolsinger, who had a 2.70 ERA in his previous three starts, gave up 10 hits, seven runs -- five earned -- and walked two in 3 2/3 innings. He struck out five.
The Diamondbacks, plagued by injuries all season, are reeling.
"When we were at our place [last month], we played these guys really good," Gibson said. "We're capable of doing that."
