The win pushed the Dodgers’ NL West ahead of 5 1/2 games over San Diego, their biggest of the season.
Rookie righthander Ryan Pepiot (1-0) started in place of Mitch White after being recalled from Triple-A Oklahoma City earlier in the day. The 24-year old Pepiot gave up one run and four hits over five innings in his fourth big league-start. He hit a career-high six and a walk.
Brusdar Graterol threw the ninth to earn his second Major League-save, both in the past week.
Colorado’s Kris Bryant went deep for the first time since last September, ending a career-worst 38-game homerless streak. His solo shot by Phil Bickford in the sixth missed the glove of a jumping Cody Bellinger on the wall in the middle. Bryant has gone 10 for 29 in seven games since coming off the injured list a week ago.
After Will Smith drew a first walk, Muncy hit a two-run shot off Germán Márquez (4-7) in the second inning to give the Dodgers a 2-1 lead. Muncy was 2 for 2 with two walks.
Betts added a solo shot – his 18th – in the third.
The Dodgers increased their lead to 4-1 on Justin Turner’s RBI single that scored Muncy, who doubled on the fourth.
Trayce Thompson’s RBI single gave the Dodgers an insurance run with two outs in the eighth. He hit a three-run homer in their 5-3 win on Monday.
Márquez gave up four runs and six hits in six innings. The righthander struckout seven and walked three.
Dodgers: OR Chris Taylor had a CT scan that revealed a fracture in his left foot. He was injured last weekend and left Monday’s game when it swelled. …Los Angeles closer Craig Kimbrel had a CT scan, but the results weren’t immediately known. He took a line drive off his back last week. … LHP Andrew Heaney (left shoulder inflammation) threw a 30-pitch bullpen. “He’s still some way down the road,” said manager Dave Roberts. … RHP Blake Treinen (right shoulder) played a day catch after throwing 30 pitches off a mound. He is not expected back before August. “We have one bullet to get him back and do it right,” Roberts said. … RHP Dustin May, who is still on his way back from Tommy John surgery, has pitched to hitters, but there is no time frame for him to embark on a drug addiction assignment.
Rockies: RHP José Ureña (0-0, 3.52 ERA) makes his Colorado debut after signing a minor league contract in mid-May. He last started on June 29 against Triple-A Sugar Land, giving up three runs and eight hits in six innings.
Dodgers: White (0-1, 3.93) is 1-1 with a 4.00 ERA and strikeouts eight in three games against the Rockies.
