The Marlins have now lost 18 of their last 22 games.
Don Mattingly was managing against the Dodgers for the first time, and his plucky club kept winning. The Dodgers had fallen into a tie for first place. The Los Angeles Dodgers have won 15 of their last 18 games when scoring more than three runs.
"It seemed a certain DL, but we'll hold out hope", Roberts said, via MLB.com's Ken Gurnick.
A year ago, the Marlins could do no wrong against the Dodgers. Running with a limp, he was thrown out at home plate to end the seventh inning.
The team's trainer came on to the field to have a look at Turner, who was favoring his right leg and was eventually helped off the field.
Overall, the Dodgers bullpen threw 3 and 2/3 innings of no-hit relief with 10 strikeouts, just the third time in the last 100 years a pen has accomplished that feat.
Los Angeles starter Hyun-Jin Ryu (2-5) allowed two runs on seven hits with three strikeouts and a walk in 5 1/3 innings.
But when an 80-mph grounder off the bat of Justin Bour ricocheted off Ryu's leg in the sixth inning, his day was over. Hatcher and left-hander Luis Avilan retired the next five Marlins batters on swinging strikeouts.
Ryu was hit by a pitch on the right bicep in the fourth inning and then took a groundball off the left knee in the sixth inning. The Marlins went 0 for 7 with runners in scoring position.

Joc Pederson singled before Puig crushed a 94-mph fastball deep into the pavilion in left-center for his team-leading eighth homer.
Jansen seemingly did everything Thursday, even batting in the eighth and getting an infield single, the second hit of his major league career.
The Dodgers loaded the bases in the first on singles by Chase Utley, Corey Seager and Turner.
