Helped by their third series sweep of the Rockies this season, the Dodgers increased their NL West lead to three games over San Diego, which lost 2-1 at home to Cincinnati.

Betts went 4 for 5 with five RBIs, capped by his seventh career slam on a 3-0 pitch from reliever Anthony Molina to make it 8-0. Andy Pages and Ben Rortvedt singled and Shohei Ohtani reached on catcher's interference to load the bases.

Teoscar Hernández followed with a solo shot off Angel Chivilli, his third homer in two games.
