LOS ANGELES -- Matt Kemp celebrated his 30th birthday on Tuesday. His 180 career home runs and 643 RBIs rank second in Dodgers history, behind Duke Snider, for a player under 30. Impressive company, but the Dodgers are more excited by the fact Kemp is looking more and more like he did the year he turned 28.Since the All-Star break, Kemp's 49 RBIs trail only Adrian Gonzalez. His 15 home runs trail only Giancarlo Stanton. And this could just be the start of things for Kemp, who -- if he can stay healthy -- could be the Dodgers' most important hitter for the first time since the beginning of the 2012 season.
