Elian Herrera had two hits, three RBI and a run scored, and Juan Uribe had two hits -- including an RBI double -- and scored a run for the Dodgers in the opener of a three-game series.
Ronald Belisario (2-0) gave up a leadoff home run to Alex Rios in the top of the eighth that tied the score 6-6. Belisario got the win -- the Dodgers' fourth victory in six games -- when Loney scored on a wild pitch by Matt Thornton (2-4) in the bottom of the eighth.
Loney reached on a one-out single and, after Dee Gordon drew a walk, Loney took third on a fielder's choice. Bobby Abreu came in to pinch-hit for Belisario and Loney scored on the wild pitch.
Kenley Jansen was perfect in the ninth, earning his 11th save.
Rios homered twice while Adam Dunn homered once for Chicago, which has lost three straight.
