Rookie Walker Buehler tossed one-hit ball into the seventh inning, Cody Bellinger and Max Muncy slugged two-run homers, and the Los Angeles Dodgers routed the Colorado Rockies 5-2 to earn a record sixth consecutive NL West title in a tiebreaker game. Jon Lester will start for Chicago. Colorado has not yet named a starter, but Antonio Senzatela may get the call.
