PHOENIX -- Cubs right-hander Jake Arrieta hit a two-run home run in his 13th consecutive regular-season victory, and Jorge Soler added a homer and two RBIs in Chicago's 7-3 victory over the Arizona Diamondbacks on Sunday at Chase Field.
Reigning NL Cy Young winner Arrieta (2-0) gave up three runs in seven innings while making his 22nd straight regular-season quality start. He gave up eight hits and struck out six without issuing a walk. He has not lost since July 25, 2015.
Soler broke a 3-3 tie with his leadoff homer in the sixth inning off Arizona right-hander Shelby Miller, and the Cubs (5-1) added three runs in the final three innings for their third victory in the four-game series.
Tommy La Stella had three hits and an RBI in his first start of the season, and Miguel Montero added two doubles and an RBI for the Cubs, who play their home opener Monday against the Cincinnati Reds.
Paul Goldschmidt and rookie Socrates Brito each had two hits and a homer for Arizona (2-5), and Jake Lamb contributed two hits and an RBI.
Miller (0-1) gave up four runs and seven hits in five-plus innings. He was lifted after Soler homered and La Stella singled to open the sixth.
Miller, who struck out six and walked two, has given up 10 runs in 11 innings in his first two starts after being acquired from Atlanta in the offseason.
Arizona starters had a 7.96 ERA in the seven-game homestand, giving up 33 earned runs in 37 1/3 innings.
After Montero's one-out double off the center field fence in the second inning, Arrieta hit a 3-2 fastball from Miller deep into the left field seats for a 2-0 lead. Arrieta has homered in two his past four regular-season starts.
La Stella singled to open the fourth inning and scored on Montero's second double off the center field wall.
Goldschmidt homered to lead off the last of the fourth, breaking Arrieta's 32-inning streak of scoreless innings in the regular season.
Lamb singled home David Peralta to make it 3-2 later in the fourth inning, and Arizona tied it on Brito's first career home run in the fifth.
Soler led off the sixth with his first homer to give the Cubs a 4-3 lead.
Soler had a sacrifice fly and La Stella a run-scoring single off Randall Delgado for a 6-3 lead in the seventh inning.
