Ronald Acuna's abdominal strain cast a shadow over Atlanta's 13-4 victory over the Chicago Cubs on Sunday night, even after the Braves bashed four homers in the first inning against Kyle Hendricks.

Freddie Freeman, Travis d'Arnaud, Ehire Adrianza and Guillermo Heredia connected during Atlanta's fast start, and Heredia added his first career grand slam in the sixth for his first multihomer game. But the Braves' big concern after the win was the status of Acuna, who departed in the fourth after he got banged up during a tough trip around the bases.

Heredia finished with a career-high six RBIs, and d'Arnaud drove in three runs. Bryse Wilson (1-0) pitched five innings of three-run ball in his first appearance of the season.

Anthony Rizzo hit two solo drives for Chicago, which lost for the sixth time in eight games. It was Rizzo's first multihomer game since Aug. 29 at Cincinnati and No. 19 for his career.

The Cubs bashed six homers during Saturday's 13-4 victory, but it was the Braves showing off their power in the rubber game of the weekend set.

Freeman kicked it off with a one-out solo drive that cleared the bleachers in right for his fifth homer, traveling an estimated 421 feet. D'Arnaud connected for a two-run shot, Adrianza belted a solo homer and Heredia capped Atlanta's six-run first with another two-run drive.

The Braves hit four homers in the first inning for the first time since May 28, 2003, against Cincinnati. The Cubs allowed four homers in an inning for the first time since the seventh on July 4, 2010, against the Reds.

Hendricks (0-2) was tagged for seven runs and seven hits in four innings in his first start since April 7. The right-hander was slated to pitch Tuesday at Milwaukee, but he was scratched because of an illness.

Following a day off, RHP Jake Arrieta (2-1, 3.18 ERA) starts Tuesday night in the opener of a three-game series against the New York Mets. RHP Taijuan Walker (0-0, 2.61 ERA) goes for the visiting Mets.
