Seiya Suzuki hit his fourth home run, extending an impressive start to his major league career, and the Chicago Cubs defeated the Colorado Rockies 6-4 on Sunday.

Willson Contreras also went deep for the Cubs. Nick Madrigal had three hits and Nico Hoerner drove in two runs.

Suzuki is batting .400 and has hit safely in eight straight games with an at-bat. The 27-year-old outfielder from Japan has reached base in all nine games with the Cubs.

Rowan Wick (1-0) won in relief and David Robertson earned his third save.

Ryan McMahon homered for the Rockies.

The Cubs roughed up Colorado starter Austin Gomber (0-1) for five runs - four earned - in 4 1/3 innings. Contreras hit a solo homer in the first, Hoerner had a two-run double in the second and Frank Schwindel made it 4-0 with an RBI single in the third.

Gomber exited in the fifth after he intentionally walked Suzuki to load the bases. Yan Gomes hit an RBI single off reliever Ashton Goudeau.

Suzuki wasn't bothered by the intentional walk.

Chicago starter Drew Smyly struck out four in 4 2/3 innings and left after a single by Yonathan Daza put runners on first and second with two outs. Scott Effross got Connor Joe to ground out to end the inning, but the Rockies came back in the sixth.

Elias Diaz's RBI single gave Colorado its first run and McMahon hit his first homer of the year off Michael Rucker to make it 5-3.

Suzuki's solo homer in the seventh made it a three-run game.

Colorado loaded the bases twice in the bottom of the seventh but managed just one run on Kris Bryant's sacrifice fly.

Chicago third baseman Patrick Wisdom was hitting .048 after going 0 for 4 on Thursday night but found his groove the rest of the weekend. He had two doubles Friday night and followed that with three hits in Saturday night's loss. He continued to produce with another double and two walks Sunday.

Wisdom had five doubles in the series and raised his batting average to .233.

Kyle Hendricks (0-1, 7.00 ERA) opens a home series against Tampa Bay on Monday night.
