Yoshinobu Yamamoto threw six scoreless innings to help lead the visiting Los Angeles Dodgers to an 8-0 win over the Arizona Diamondbacks on Wednesday night.
Yamamoto (3-1) gave up five hits and two walks while striking out five. The rookie lowered his ERA from 3.54 to 2.91, and hasn’t lost a game since his debut on March 21. Mookie Betts went 3-for-5 and drove in two runs, and Andy Pages also drove in two for the Dodgers, who have won eight of their past 10 games.
Los Angeles got on the board in the top of the second inning. Kike Hernandez drew a one-out walk and Pages followed with a two-run homer — his third of the year — off Arizona starter Jordan Montgomery.
Miguel Rojas then doubled, Chris Taylor walked, and Austin Barnes drove in the third Dodgers run on an RBI double. Betts followed with a two-run single to increase Los Angeles’ lead to 5-0.
After Yamamoto threw a scoreless bottom of the second, Will Smith led off the top of the third with his fourth home run of the year, giving the Dodgers a 6-0 advantage.
Montgomery (1-2) was pulled after finishing the inning. He went three innings and allowed six runs on six hits with three walks, striking out one. The left-hander was replaced with 22-year-old Blake Walston, who made his major league debut.
Walston held the Dodgers scoreless until the seventh. Freddie Freeman walked to open the inning and Teoscar Hernandez hit a one-out single. Kike Hernandez walked to load the bases. Walston struck out Pages but walked Rojas, forcing in Freeman from third.
Brandon Hughes replaced the rookie, but he walked Taylor to put the Dodgers up 8-0.
Walston threw 3 2/3 innings and allowed three hits, two runs and four walks, striking out five.
Yamamoto was pulled for reliever J.P. Feyereisen in the bottom of the seventh.
Feyereisen and Gus Varland combined for three scoreless innings in relief. Varland retired Jake McCarthy on a groundout to end the game.
