Miami has dropped five straight, and fallen back to .500. In each of those outings, a starter has been unable to log as many as six innings.
On the grander scale, the club is a mere 3-15 on the road this season, including 1-5 on its 11-game West Coast swing. Turner, charged with five runs (four earned) in 5 1/3 innings, is now 0-10 lifetime in 17 road starts.
"We're in that funk right now, where we can't get anything going," manager Mike Redmond said. "We need a quality start, and we can't get the runs that we need. For whatever reason, we've been able to do it at home."
Tuesday was another reminder of the baffling splits between home and away. At Marlins Park, Miami is 17-5.
"I'm not sure exactly how to explain it, but we have to get it figured out and find ways to win some ballgames on the road," Redmond said. "For me, it starts with the pitching, but offensively, we've got to lock it in and have some better at-bats."
Beckett, the 2003 World Series MVP for the Marlins, silenced his former team. The lone run he allowed came on Marcell Ozuna's sacrifice fly, which scored Garrett Jones, who doubled. But the run was unearned due to Drew Butera's passed ball.
Beckett picked up his first win of the season, and his first overall since Sept. 30, 2012.
Even though Beckett (1-1) hadn't won this season, he has pitched effectively.
"More of the same from Josh," Dodgers manager Don Mattingly said of Beckett. who has a 2.38 ERA.
On Yasiel Puig bobblehead night, the Dodgers slugger had two hits, a walk and an RBI.
"To me," said Mattingly, "he's growing up right before our eyes."
Miami's Giancarlo Stanton extended his career-high hitting streak to 15 games with a single in the first inning.
"We went from having eight guys hitting [at home] to one," Redmond said, meaning Stanton.
In the fourth inning, Stanton tapped a slow roller to third for an infield single. He swiped second, and advanced to third with one out, where he was stranded.
The Marlins wasted another chance in the fifth inning, after Derek Dietrich singled and was left at third when Adeiny Hechavarria grounded to third.
"We couldn't get anything going against Josh," Redmond said. "He shut us down. We had an opportunity there to score a run that could have at least given us a little bit of momentum. But it didn't happen.
"It looked to me like it was going to be a close game. Had we been able to answer and taken a bit of pressure off our pitching with a couple of runs, could have been the difference. We weren't able to do that. Wasted opportunities came back to haunt us."
Turner was in command for five innings, but the Dodgers showed their explosiveness in the sixth, scoring five times.
The inning started off harmlessly enough when Turner retired Beckett on a routine fly to center.
From there, the game got away from Turner. Dee Gordon doubled to right, showing his speed by hustling all the way on what would have been a single for many players. Puig walked on four pitches. In position to get a double play to get out of a jam, Turner ran the count full to Ramirez, who lined a two-run double to left. Adrian Gonzalez delivered an RBI double, and scored on Matt Kemp's single, and Turner was lifted for Dan Jennings.
Turner was upset about failing to put Gordon away, and it opened up the big inning.
"I got ahead of him, 0-2," Turner said. "I just didn't put him away. When he's on base, obviously, he's fast. So your attention is somewhat divided. That's really the at-bat that changed the game."
Ramirez got the scoring going with his double.
"It was a fastball that came back over the middle of the plate," Turner said. "I got behind in the count, and worked it back. Obviously, he took advantage of a mistake."
