Yasiel Puig's three-run homer highlighted a five-run first inning and the Los Angeles Dodgers routed the San Francisco Giants 9-3 on Wednesday night, extending their NL West lead to six games with 10 remaining. The Dodgers pounded out 12 hits in taking two of three from the rival Giants, who remained tied in the NL wild-card race after both the Mets and Cardinals lost earlier. The Dodgers conclude the regular season with three games at San Francisco next week.
