Mike Brosseau's first career pinch-hit homer snapped a tie in the seventh inning, and the Milwaukee Brewers beat the Cubs 5-4 for their first victory of the season.

Willy Adames and Rowdy Tellez also went deep, helping the reigning NL Central champions overcome a shaky performance by starter Freddy Peralta. Christian Yelich had two hits and drove in a run.

After Brosseau connected, Milwaukee's vaunted bullpen took over.

Brad Boxberger (1-0) worked the seventh, stranding a runner on third when Jonathan Villar was retired on a close call at first base that was upheld by a replay review. Devin Williams then got three outs before Josh Hader pitched a 1-2-3 ninth for his first save.

Seiya Suzuki hit his first major league homer for Chicago, and Marcus Stroman pitched five effective innings in his Cubs debut. The Cubs were trying to go 3-0 for the first time since 2016.

With two outs and runners on first and second in the first, Suzuki drove a 3-1 pitch from Peralta deep to center field.

Stroman allowed one run and two hits. The right-hander exited with a 3-1 lead, but the Brewers jumped all over Jesse Chavez in the sixth. Yelich doubled home Adames, and Tellez hit a one-out drive to right-center for his first homer of the season.

The Cubs tied it at 4 on two wild pitches by Jake Cousins with two outs in the bottom half, but the Brewers went ahead to stay on Brosseau's 17th career homer.

Peralta, who went 10-5 with a 2.81 ERA for Milwaukee last year, allowed three hits, struck out six and walked four in four innings.

It was a tough opening series for the Brewers' front three starters of Corbin Burnes, Brandon Woodruff and Peralta. They yielded 13 earned runs and 10 walks in 12 2/3 innings.
