"On contact, I just thought I got my job done," Turner told reporters. "I hit it pretty good. In Citi Field, who knows what's going to happen out there, if it's going to hang up or not. I guess lucky for me, it hit off the tip of his (Kemp's) glove."
Dodgers (15-19) left fielder Andre Ethier was 0-for-4 at the plate with a walk ending his consecutive game hit streak at 30 games.
"Right now, I'm more disappointed in what we're going through," Ethier said of the team's four-game losing streak.
"Putting the streak aside, I had a couple opportunities to drive in a run. That's frustrating. Maybe it was something where I can go up there and drive the ball a lot more, maybe that's what we need more of.
"I thought maybe when the streak ends, our thing (losing run) would end. This makes for a tougher pill to swallow. Two negatives don't make a positive in this situation."
Byrdak pitched a scoreless eighth inning to collect the win, and Francisco Rodriguez pitched a perfect ninth inning for his ninth save of the season.
New York (15-18) scored two runs in the second inning to open a 2-0 lead for Dillon Gee, who was a late replacement for scheduled starter Chris Young who could not get loosened up in the bullpen.
