Max Muncy busted out of a season-long slump with a grand slam and a three-run home run, Julio Urias threw six sharp innings and the Los Angeles Dodgers opened a three-game road series against the rival San Francisco Giants with a 9-1 romp Monday night.

Muncy also singled, all after Mookie Betts had led off the game with his second homer of the season for the Dodgers, who snapped a three-game losing streak.

Wilmer Flores homered for the Giants, his second of the year, but couldn't prevent a third loss in the last four games for San Francisco and the third consecutive season-opening defeat for ace Logan Webb.

Thanks to Betts' homer, which came on the game's sixth pitch, the Dodgers led 1-0 entering the third before two singles set the stage for Muncy's first homer, a three-run shot.

Flores got the Giants within 4-1 in the fourth, but the visitors broke the game open in the seventh when, with two outs, Betts singled in James Outman, who had walked.

Freddie Freeman and Will Smith followed with singles to load the bases, and Muncy in turn emptied them and made it a blowout at 9-1 with his third career grand slam to complete the game's scoring.

The two homers raised his career total at Oracle Park to nine, the second most at the site of any opponent. He has 13 career homers at Coors Field in Denver.

Muncy finished 3-for-3 with a walk after having gone 1-for-13 with five strikeouts in his previous four games. For the season, he'd been 4-for-33 (.121) with one homer and two RBIs.

Urias (3-0) limited the Giants to one run and four hits in his six innings. He walked two and struck out eight.

Webb (0-3) also was pulled after six innings, during which he served up four runs on six hits. He walked one and struck out six.

Betts had three hits, two RBIs and scored three times for the Dodgers, who outhit the Giants 10-7. Freeman scored twice after two hits.

J.D. Davis had two of the Giants' seven hits on a night when Flores' homer was their only extra-base hit.
