PHOENIX (Interstat) — The Arizona Diamondbacks used a pair of home runs, including a two-run shot by Ketel Marte in the eighth inning, to defeat the Los Angeles Dodgers 4-1 on Monday night at Chase Field.

The victory before a crowd of 31,410 snapped a three-game losing streak for the Diamondbacks and improved their record to 32-27. The Dodgers, who entered the game with the best record in the National League, fell to 38-22.

Taylor Clarke earned the win with a scoreless inning of relief, improving to 2-1. Paul Sewald recorded his 15th save with a perfect ninth inning. Emmet Sheehan took the loss for Los Angeles, dropping to 3-2 after allowing two runs over 6 2/3 innings.

The game was a pitcher’s duel for much of the night, with only one run crossing the plate through the first five innings. The Dodgers struck first in the third inning, capitalizing on a pair of doubles. Shohei Ohtani led off with a double to center field, his 13th of the season. Andy Pages followed with a double to center, moving Ohtani to third. Freddie Freeman grounded out to third base, driving in Ohtani for a 1-0 Los Angeles lead.

The Dodgers had opportunities to add to their lead but could not deliver. In the second inning, Mookie Betts singled and Kyle Tucker walked, putting two on with no outs. Will Smith flied out to center, but Betts tagged and moved to third. Max Muncy reached on a fielder’s choice as Betts was thrown out at home. Miguel Rojas singled to load the bases, but Alex Call popped out to end the inning.

Dodgers starter Emmet Sheehan was sharp early, retiring the first 10 batters he faced. The only Diamondbacks hit through four innings was a double by Corbin Carroll in the first, but he was left stranded. Sheehan struck out three and walked none in the early going.

The Diamondbacks finally broke through in the sixth inning. With one out, Tommy Troy hit his first home run of the season, a solo shot to left field that tied the game at 1-1. It was a historic moment for the rookie left fielder, who had entered the game hitting just .212.

The game remained tied until the seventh inning, when the Diamondbacks took the lead for good. Nolan Arenado, who had struggled against Sheehan in his first two at-bats, drove a pitch to left-center field for his eighth home run of the year, giving Arizona a 2-1 advantage.

Sheehan was replaced after allowing the home run, having given up two runs on three hits over 6 2/3 innings. He struck out five and walked none.

The Diamondbacks added insurance in the eighth inning against the Los Angeles bullpen. After Tommy Troy reached on a bunt single, Marte launched his 10th home run of the season to left field, a two-run shot that extended the lead to 4-1.

Marte finished the game 1-for-4 but made his lone hit count. Troy had two hits, including his home run and the bunt single that set up Marte’s blast. Arenado also homered and drove in a run.

The Dodgers managed only six hits in the game, with Ohtani collecting two of them. Betts, Rojas, Pages and Freeman each had one hit. Los Angeles went 0-for-5 with runners in scoring position and left six runners on base.

Diamondbacks pitching was effective throughout. Starter Brandyn Pfaadt worked five innings of one-run ball, allowing five hits while striking out three and walking two. Clarke entered in the sixth and retired the side in order, striking out two. Sewald closed the door in the ninth, allowing no hits and striking out one.

The game was played in 2 hours, 18 minutes, a brisk contest that featured just nine combined hits and two walks.

For Arizona, the win was a much-needed bounce back after a difficult road trip. The Diamondbacks had lost three straight in Seattle, including a pair of one-run decisions in extra innings. The Dodgers had won four of their previous five games, including a 9-1 victory over Philadelphia on Sunday.

The series continues Tuesday night at Chase Field as the two teams play the second game of a four-game set. The Dodgers will send right-hander Gavin Stone to the mound, while the Diamondbacks will counter with left-hander Eduardo Rodriguez.

The most important sequence of the game came in the bottom of the eighth inning. With the Diamondbacks holding a 2-1 lead, Tommy Troy led off with a bunt single that caught the Dodgers defense off guard. The bunt was perfectly placed, and Troy beat the throw from third baseman Max Muncy. That brought Marte to the plate, and on a 1-1 pitch, he lined a fastball over the left-field wall. The two-run homer gave Arizona a three-run cushion and effectively put the game out of reach. The Dodgers’ offense had been held in check all night, and the extra runs proved decisive.

The Diamondbacks also got a key defensive play in the eighth inning when first baseman Ildemaro Vargas started a double play to erase a leadoff single by Ohtani. After Ohtani singled to lead off the eighth, Pages flied out to right field. Freeman then grounded to first, where Vargas stepped on the bag and threw to shortstop Geraldo Perdomo to double off Ohtani. The play ended the inning and killed any hopes of a Dodgers rally.

Interstat’s game simulator had projected a final score of Los Angeles 8, Arizona 7, while the ELO system gave the Dodgers a 61.20 percent probability of winning. The Dodgers were installed as a pregame favorite with a spread of minus-1.5. The total of five runs scored went under the over-under line of nine.
