Shohei Ohtani and Freddie Freeman homered in a seven-run first inning and the Los Angeles Dodgers held on for an 8-7 victory over the Colorado Rockies on Wednesday to complete a three-game home sweep.

Ohtani also had an RBI single in the first inning as the Dodgers sent 12 batters to the plate. However, Los Angeles right-hander Bobby Miller struggled in his first start of the season, giving up six runs on eight hits in three innings. He struck out seven and walked one.

Freeman added a double to go along with his homer as Los Angeles improved to 10-2 at home this season. Andy Pages drove in three runs for the Dodgers.

Michael Toglia hit a grand slam and Mickey Moniak followed with a home run for the Rockies, who took their sixth straight loss, matching their worst skid of the season.

Colorado starter German Marquez (0-3) did not make it out of the first inning, giving up seven runs on six hits and a walk while recording two outs. Marquez made his fourth start of the season, one short of his combined total from his previous two years following multiple elbow injuries.

In a game that included 13 total runs in the first three innings, the Rockies went on top 1-0 in the first on a double from Kyle Farmer.

The Dodgers started their big first inning with home runs from Ohtani and Freeman within the first three batters. Pages added a two-run single, and Austin Barnes delivered a two-run double before Ohtani hit his RBI single for a 7-1 advantage.

The Rockies stormed back in the third with two singles and a walk before Toglia took Miller deep to center field for his second career grand slam. Moniak followed with a home run to left field to cut Colorado's deficit to 7-6.

The Dodgers wedged some breathing room in the fifth when Max Muncy singled off Luis Peralta, went to second on a wild pitch and scored on a Pages single.

Ben Casparius (1-0) allowed one run over three innings of relief for Los Angeles. Left-hander Tanner Scott pitched a scoreless ninth inning for his sixth save.
