Matt Kemp hit a two-run homer to become the first Dodgers player in 70 years to lead the NL in home runs and RBIs, and Los Angeles held off a late rally to beat the playoff-bound Arizona Diamondbacks 7-5 on Wednesday night. Kemp hit his 39th homer in the seventh inning to pass Milwaukee's Prince Fielder for the league lead and finished with 126 RBIs, second-most in Dodgers history to Tommy Davis' 153 in 1962.
