SAN DIEGO -- The Home Run Derby comes to Petco Park next July, but the Dodgers staged their own edition Friday night. In an 8-4 victory over the Padres, Los Angeles launched five home runs, including three taters in a decisive five-run sixth inning. The win, coupled with a Giants loss, moves the Dodgers 7 1/2 games up in the National League West, putting a third straight division title squarely on the horizon. Justin Ruggiano's pinch-hit, two-run shot in the sixth gave L.A. a 5-3 lead before Adrian Gonzalez and Chase Utley went back-to-back later in the frame.
