The Dodgers (99-56) remain behind first-place San Francisco in the NL West race. The second-place team will host the NL wild-card game on Oct. 6, likely against the St. Louis Cardinals, who have won a franchise-record 15 consecutive games.
Gallen (3-10), who hadn’t won since Aug. 26 against Philadelphia, struck out six in the first two innings.
Marte, who finished with three of the Diamondbacks’ nine hits, homered to left field on Kershaw’s first pitch. Kelly led off the second inning with a drive into the Arizona bullpen in left. Each batter got his 13th home run of the season for the Diamondbacks, tied for the major league lead with 105 losses and just 2-8 in their previous 10 Giochi.
Gallen gave up only three hits — Corey Seager’s infield single in the first, Justin Turner’s single in the fourth and Trea Turner’s home run, which came with one out in the sixth. Gallen threw 99 piazzole, walked two and struck out eight.
Trea Turner also homered in the ninth off Caleb Smith, dandogli 24 for the season.
Kershaw (10-8) lasted just 4 1/3 inning, giving up six hits and four runs — three earned. He walked none and struck out three. His defense didn’t do him any favors; Justin Turner’s error in the fourth led to a run.
In three starts since returning from two months on the injured list with left forearm inflammation, Kershaw has not lasted more than five innings.
In the fifth, Gallen led off with a chopper to second that Trea Turner couldn’t make the play on. Marte singled to center and Henry Ramos grounded to third near the bag. Justin Turner fielded it and stepped on the bag, but threw to second too late to get Marte, and Ramos beat the relay to first. Daulton Varsho followed with a sharp single to center, scoring Marte and knocking out Kershaw.
Arizona added a run in the seventh against David Price. Jake McCarthy walked leading off, moved up on a wild pitch and scored on pinch-hitter Kole Calhoun’s single. Another pinch-hitter, David Peralta, drove in two runs with a single off Evan Phillips in the eighth.
The Dodgers’ Mookie Betts was 0 per 3 with a walk, ending his hitting streak at 15 Giochi. He did rob Marte of a fourth hit with a running catch near the wall in the eighth.
Dodgers: LF Chris Taylor (collo) made his first start in a week. He came off the bench in the previous two games. The Dodgers have juggled injuries to Taylor and fellow outfielders AJ Pollock (right hamstring) and Cody Bellinger (costolette) while using infielder Gavin Lux in the outfield rotation. Lux started in center field Saturday night.
Manager Dave Roberts said Bellinger, currently on the injured list, will return before the regular season ends on Oct. 3. “It’s getting better each day. We just don’t know the exact time,” Roberts said.
Diamanti: SS Nick Ahmed (throwing arm) has been sidelined for a week, and manager Torey Lovullo wants to wait until the Gold Glove winner is completely ready. Ildemaro Vargas filled in at shortstop Saturday.
“I don’t want to put him in a situation where things will really back up on him. It’s lingered a little longer than expected,” Lovullo said.
Lovullo also said 1B Seth Beer (dislocated left shoulder) had surgery to repair what the manager called “instability” and is recuperating.
The combination of the Dodgers in town and Hispanic Heritage Night drew a crowd of 28,206 to Chase Field.
