The Dodgers held a 4-2 lead after six innings, dropping them to 17-2 when leading after six innings this season.
Carlos Frias pitched into the seventh inning in a start for the first time in his career, but that lasted all of one batter, removed after a leadoff single by Adeiny Hechavarria. Adam Liberatore's streak of 16 straight batters retired ended with a perfect bunt single by Ichiro Suzuki and a traditional single by Dee Gordon loaded the bases with nobody out, and ended Liberatore's night.
Chris Hatcher allowed consecutive hard singles to center field by Martin Prado and Giancarlo Stanton, plating the three inherited runs to snap the Dodgers' five-game winning streak.
Gordon, held hitless in the first two games of the series, doubled to open the third inning and later scored on a ground out. He had four hits on the night, scoring twice, and leaves town hitting .426.
Gordon's 17 multi-hit games this year are tied for the most in the majors with Matt Carpenter of the Cardinals.
Miami tacked on another run with three straight two-out singles in the fourth, including an RBI hit from pitcher Jarred Cosart. On the mound, Cosart allowed four runs but left in the sixth inning with tightness in his right hamstring.
The Dodgers cut the deficit to 2-1 in the fourth inning with two balls hit to right and not caught by Stanton - a triple by Alex Guerrero and ball hit by Howie Kendrick called an out and somehow upheld by replay review. Manager Don Mattingly was less than enthused with the call, and was ejected for arguing by first base umpire Jerry Layne. For you non-lip readers:

After the game, Mattingly was more subdued but still disagreed with the call.
"They show it on the big screen and we see [the ball] bounce, you just know it's going to get overturned and then it doesn't. It's frustrating," Mattingly said. "There's just no way in the world that ball bounces that way up into the glove without hitting the ground.
"It's the same thing as always, not enough evidence to overturn it. It's just wrong. It will get fixed, somehow, some way.
"It's not worth talking about anymore, but it did cost us a run in a one-run game."
Back-to-back home runs in the fifth inning by Kiké Hernandez and Joc Pederson gave the Dodgers a 4-2 lead, one the Dodgers took into the fateful seventh inning.
Four Marlins relievers, including old friend Bryan Morris, retired 10 of the 11 batters they faced. With Steve Cishek demoted from the closer role after his blown save on Monday, A.J. Ramos closed out the ninth for the Marlins, retiring the Dodgers in order, with two strikeouts.
