Michael Busch drove in four runs to lead the host Chicago Cubs to an 8-4 win over the Arizona Diamondbacks Sunday.

Busch doubled and scored a run in the second and broke the game open for good with a three-run triple in the fifth as Chicago finished the three-game sweep with its 11th straight win at home.

Matthew Boyd (2-1) picked the win. The southpaw gave up four hits and two earned runs over six innings, walking one and fanning five in 94 pitches. The quality start was the Cubs' seventh in their last 10 home games.

Chicago tied a season high with six extra-base hits. Busch, Nico Hoerner, Moises Ballesteros, Seiya Suzuki and Carson Kelly all contributed a pair of hits.

The Cubs extended a 3-2 lead with a three-run fifth.

Ballesteros led off with a walk and Alex Bregman reached on a fielder's choice when Nolan Arenado's throw was too late to get Ballesteros at second.

Ian Happ loaded the bases with a walk and Busch tripled into the right-field corner to clear the bases and give Chicago a 6-2 lead.

The triple chased Diamondbacks starter Merrill Kelly (1-3). The veteran right-hander went 4 1/3 innings, giving up eight hits and six earned runs. He struck out five and walked three in 92 pitches.

The Diamondbacks opened the scoring in the second when Arenado doubled with one out and Gabe Moreno hit his first home run of the season deep to left field for a 2-0 lead.

The Cubs cut the lead in half in the bottom of the inning when Kelly singled in Busch with two outs.

Chicago took the lead for good in the third when Hoerner singled to deep short and Ballesteros smashed an opposite-field home run to left-center for a 3-2 advantage.

The Cubs scored a pair of insurance runs in the seventh when Happ led off with a walk and Suzuki doubled into the left-field corner.

Busch drove in his fourth run of the game with a deep sacrifice fly to right to make it 7-2 Cubs and Kelly singled in Suzuki to give Chicago an 8-2 lead.

D-backs pinch-hitter Adrian Del Castillo hit a two-run homer with two outs in the ninth to finalize the scoring. Lourdes Gurriel Jr. went 2-for-3 with a run for the visitors.
