Mookie Betts, Trea Turner and Justin Turner all hit home runs in a five-run sixth inning and the Los Angeles Dodgers rallied for a 7-6 victory over the visiting Arizona Diamondbacks on Tuesday in the opener of a day-night doubleheader.

Betts had three hits to give him at least one hit in 17 of his last 20 games after a slow start when he was batting just .171 over his first 10 contests. The Dodgers won their third consecutive game after a season-long four-game losing streak.

Christian Walker and Alek Thomas each hit home runs for the Diamondbacks, who dropped their fourth consecutive game to match a season-long losing streak.

The Diamondbacks took a 3-0 lead in the third inning on a Pavin Smith RBI single and a two-run home run from Walker, his eighth of the year and second of the series.

The Dodgers broke through in the fourth inning against Diamondbacks starter Tyler Gilbert on a solo home run from Will Smith, his third.

Los Angeles had a leadoff single from Hanser Alberto in the sixth and Betts followed with a home run, his eighth, to tie the score 3-3. Trea Turner hit a one-out home run, increasing the lead to 4-3.

Gilbert (0-2) retired Smith on a grounder for the second out of the sixth before Max Muncy walked and Justin Turner hit a home run to center, his third, for a 6-3 advantage.

The Diamondbacks scored twice in the seventh on Thomas' second career home run and an RBI single from Ketel Marte to pull within a run at 6-5. The Dodgers added a run in the seventh on an RBI single from Freddie Freeman.

Marte had a run-scoring infield single in the ninth for Arizona before Dodgers closer Craig Kimbrel finished off his seventh save.

Dodgers rookie starter Ryan Pepiot gave up three runs on two hits over four innings with three walks and five strikeouts. Justin Bruihl (1-1) picked up the win by allowing just one hit and no walks in 1 1/3 scoreless innings.

Dodgers manager Dave Roberts was ejected in the ninth for arguing a non-call on a check-swing appeal.
