ATLANTA (AP) — Arizona manager Kirk Gibson found no fault with Josh Collmenter after the right-hander settled down in the third inning.
Collmenter gave up a career-high 11 hits, and the Diamondbacks couldn't solve Ervin Santana or the Atlanta bullpen in a 5-2 loss to the Braves on Friday night.
"He went out there and did the best he could and got through six innings. We were unable to score runs," Gibson said.
Freddie Freeman drove in two runs, and Santana won his second straight start for Atlanta, which stretched its winning streak to eight games.
Arizona began the night tied with Houston for the most losses in the majors with 51. The Diamondbacks have lost seven of 11.
"We're trying everything we can to turn around things, but it's not happening," third baseman Martin Prado said. "We're trying to have good at-bats and everything. I feel like we're pretty close. There's a bunch of guys having good at-bats."
After earning three victories from June 20-28, Collmenter (7-5) allowed five runs, one walk, and struck out three in six-plus innings.
The Braves have won 10 of 11 to move 10 games over .500 for the first time since April 29. They lead the NL East by 1½ games.
Santana (7-5) gave up six hits and two runs with one walk and six strikeouts in 7 1-3 innings.
The Braves made it 2-0 in the first on Freeman's RBI single and Jason Heyward's RBI groundout.
Atlanta went up 4-1 in the third on Andrelton Simmons bases-loaded RBI single and Justin Upton's RBI walk, but Collmenter stranded the bases loaded when Heyward popped out.
Collmenter's night ended after Simmons led off the seventh with a double. Oliver Perez, the next Arizona pitcher, allowed another RBI single by Freeman to make it 5-1.
"I wasn't missing so much up in the zone as missing over the plate, enough for them to get a piece of the ball," Collmenter said. "I just didn't capitalize on my opportunities when I could have made a pitch."
