Mike Marshall's two-run double tied the score and rookie R.J. Reynolds squeezed home Pedro Guerrero with the winning run in a four-run ninth as host Los Angeles beat Atlanta.
The Dodgers lead the Braves in the NL West by three games.
Jose Morales doubled in the Dodgers ninth for his 107th career pinch hit and Jim Anderson ran for him. After Steve Sax walked, Garber relieved and struck out Bill Russell, but Dusty Baker looped a single to right-center, loading the bases. After Cecil Espy ran for Baker, Guerrero walked on a 3-2 pitch, forcing in a run. Marshall then doubled to the base of the wall in right field, tying the score. Greg Brock was then walked intentionally, loading the bases. Reynolds, called up Sept. 1 from San Antonio of the Texas League, laid a bunt down the first base side, allowing Guerrero to score without a play.
"I'm like a little kid right now," said Reynolds, who was playing because Ken Landreaux has an ankle injury. "This has got to be my greatest moment. When the ball hit the bat, I knew the game was over."
Dodger Manager Tommy Lasorda said he's using rookies, despite the toughness of the race because, "I don't ask kids how old they are. I just put them up and tell them to do the job. We're going to make men out of them real quick."
