Joc Pederson hit two homers, Max Muncy added a three-run shot and the Los Angeles Dodgers moved back into first place in the NL West with an 8-2 victory over the Colorado Rockies on Monday night. Dodgers starter Hyun-Jin Ryu (5-3) pitched seven scoreless innings, throwing 93 pitches to match a season high. The Rockies entered this showdown series with a half-game lead on Los Angeles, but the teams switched places as the Dodgers unleashed the high-powered offense that helped them win three of four last weekend in St. Louis.
