Matt Kemp didn't have to run the bases on his first-inning home run nearly as hard as Eric Young Jr. had to in the top half. And the Los Angeles Dodgers' slugger drove in two extra runs in the process to put Chad Billingsley on course to win his fourth straight start. Kemp answered Young's first inside-the-park homer with his 17th of the season and first with more than one runner on base, sparking the Dodgers' 6-4 victory over Colorado on Wednesday night and helping them avoid a three-game sweep by baseball's worst pitching staff.
