The NL West leaders earned their 10th sweep of the season and first against San Diego. They extended their roll from August, when the Dodgers went 23-6 for their most successful month since moving to Los Angeles in 1958.
Greinke (14-3) won his sixth straight start for the first time since winning nine in a row over the 2008-09 seasons. The right-hander gave up two hits, struck out seven and walked two. Greinke, who came in batting .340, also singled with two outs in the fifth.
