The Arizona Diamondbacks nearly snatched another improbable win before heading to the playoffs. But Matt Kemp grabbed a piece of Dodgers history. Kemp hit a two-run homer to become the first Dodger in 70 years to lead the NL in home runs and RBIs, and Los Angeles had to withstand another late-inning grand slam to beat the playoff-bound Diamondbacks 7-5 on Wednesday night.
