Turner, who played for the Mets from 2010-13, doubled home a run in the first inning and hit a solo homer in the third to pace the Dodgers, who throttled Jon Niese for six runs in three innings. Yasiel Puig also highlighted the attack with a two-run homer.
It was more than enough to back Thomas, who allowed one run in five innings in his first career start. Subbing for Greinke during his paternity leave stint, Thomas allowed nothing more than an RBI groundout from Mets outfielder Michael Conforto, who was making his Major League debut.
"Obviously, he was really good," Dodgers manager Don Mattingly said of Thomas. "We didn't really know what to expect. We wanted him to pitch like a bullpen guy, be aggressive through the first, second and third innings. He gave us five and that was huge for us."
The Mets can only hope their offensive attack will become more balanced when trade acquisitions Kelly Johnson and Juan Uribe arrive from the Braves.
MOMENTS THAT MATTERED Puig's revival: Two batters after Turner's homer in the third inning, Puig slugged his sixth home run of the season and second in four games, driving in Scott Van Slyke, who had singled. Hampered by hamstring problems, Puig has played 51 of the Dodgers' 98 games.
Not scratched, but stomped: Nearly missing Friday's start to join Greinke on paternity leave, Niese instead stuck around for one of the worst outings of his career. Turner's RBI double and homer put him on the ropes, while Puig's two-run shot thrust Niese into a six-run deficit. Niese's wife gave birth while the game was going on, and he left afterward to join her in Ohio. More >
One for the kid: With a runner on third base and one out in the fifth, Conforto grounded a ball to the right side for his first career RBI, plating Lucas Duda. The rookie grounded out in each of his first three big league at-bats. More >
"It gave me chills," Conforto said of the reaction he received from the crowd. "One of the best feelings in the world, a really warm welcome from Mets fans. I can't say enough about how much that meant to me. I'll remember that forever."

When Niese threw his first pitch at 7:10 p.m. ET, Conforto officially became the 1,000th player in Mets history. The Mets are the 18th team to use 1,000th players, needing 54 seasons to reach that mark.
Triple-A Las Vegas scratched right-hander Logan Verrett from his scheduled start late Friday night, shortly after Niese left to be with his wife. Verrett, who posted a 0.73 ERA in six relief appearances for the Mets earlier this season, could join the club on Saturday, with Niese likely headed to the paternity leave list.
WHAT'S NEXT Dodgers: With new father Greinke now slated to start on Sunday, Zach Lee is the most likely candidate to start Saturday against the Mets at 4:10 p.m. PT, although the Dodgers haven't officially announced anything yet. Lee would be called up to make his Major League debut.
Mets: Johnson and Uribe should be on board when the Mets continue their four-game series with the Dodgers at 7:10 p.m. ET Saturday. Matt Harvey will start that game at Citi Field, looking to improve on his 4.26 ERA in July.
