Adrian Gonzalez singled in the winning run with the bases loaded in the 14th inning, lifting the Los Angeles Dodgers over the San Francisco Giants 5-4 early Tuesday in the opener of a crucial series between the NL West's top two teams. The first-place Dodgers' lead increased to 4 1/2 games over their second-place rivals after the longest game by innings for both teams this season. Giants reliever Mike Broadway (0-1) started his first inning of relief by walking A.J. Ellis and then gave up consecutive singles to Jimmy Rollins and Chase Utley to load the bases.
