ATLANTA -- The road has become a very unfriendly place for the Arizona Diamondbacks.
For the sixth time in their last eight games away from home, the D-backs came up on the wrong side of the ledger, this time by a 6-4 count to the Braves on Wednesday night at Turner Field.
By contrast, the D-backs have won 10 of their last 11 at home.
"We scored four runs, and you would hope you could be in it with these guys," D-backs manager Kirk Gibson said.
If one person could reverse that trend it figured to be starter Trevor Cahill, who came into Wednesday's start not having allowed a run in his last 20 innings on the road.
That scoreless streak came to an end quickly, as the second batter of the game for the Braves, Jason Heyward, launched a 2-0 offering into the seats in right-center.
Cahill (6-6) settled in for a time after that, keeping the Braves off the board for the next three innings.
Atlanta was able to break through again in the fifth however, capitalizing on three walks and a throwing error by Cahill to score three times and take a 4-0 lead.
After allowing a walk and a single to start the fifth, Cahill fielded a tapper back to the mound and tried to start a double play at second. His throw tailed down and away from shortstop Stephen Drew and into center field.
"I thought I made a good pitch and I was thinking double play, and I should have just taken my time and made sure to get the lead out -- especially with the pitcher coming up -- but I threw it away," Cahill said. "I picked it up and threw it however I had a grip which is probably a two-seam grip because that's usually what I'm holding, and it just kind of ran away and down on him."
As a result of the error, two of the three runs that scored that inning were unearned.
"It's a comebacker, we work on those all the time, and we expect to make that play one way or another," Gibson said. "Probably wasn't one of our cleaner games -- the error really hurt us."
In the sixth, Chipper Jones gave the Braves what would turn out to be key insurance runs and a 6-0 lead when he hit a two-run homer that sent Cahill to the showers.
"I thought it was good pitch, and I saw him swinging and I was hoping he was going to be out in front and roll something over," Cahill said. "But he's a Hall of Fame-caliber hitter and he was able to keep the barrel through the zone, so it was just one of those things where you just have to tip your cap."
Up to that point the D-backs had been unable to do much against Braves starter Tommy Hanson, who held them hitless through three innings, and allowed just four hits through six.
In the seventh, after back-to-back one-out singles by Miguel Montero and Aaron Hill, Ryan Roberts jumped on the first pitch and sent it into the bleachers in left to pull the D-backs to within three runs.
Roberts jumped on a first-pitch fastball from Hanson after being stymied by Atlanta's pitchers to that point in the series.
"That's all they've been throwing me," Roberts said of the inside fastball. "I haven't gotten to anything inside in two days. [Tuesday] that's all [Tim Hudson] was doing was pounding sinkers in. I think he threw one pitch away from me. Today was the same thing, first-pitch fastball middle in, second-pitch fastball middle in. He kept throwing it because I kept missing it, so there was no reason to switch it up. I just finally got to one. It was just a matter of getting my hands working in the right place."
One out later, Chris Young pinch-hit for Gerardo Parra and homered to close the gap to 6-4. It was the first pinch-hit homer of his career.
"I'm going out and giving us the chance to win, and when you're up 6-0 the last thing you want to do is walk guys," Hanson said. "You want to be aggressive and throw strikes. There at the end, it wasn't ideal, but I stayed aggressive, and it just so happens that they hit those balls well."
Cahill allowed six runs (four earned) in five innings to snap his four-start win streak.
Hanson, meanwhile, has won his last four decisions to raise his record to 9-4.
