LOS ANGELES -- The Los Angeles Dodgers fell into the trap of playing the only kind of game the San Diego Padres can win, games in which nobody scores many runs.But they interrupted a night of lifeless at-bats at an opportune time, the bottom of the ninth inning. Adrian Gonzalez led off with a hustle double to center field and scored on an A.J. Ellis sacrifice fly to give the Dodgers a 1-0 walk-off win Saturday night, putting them alone once again in first place.
