Jason Kubel and Paul Goldschmidt both clubbed two-run homers and Aaron Hill added a solo shot as the Arizona Diamondbacks crushed the Milwaukee Brewers, 9-2, at Miller Park.
Hill also had an RBI double and Gerardo Parra added two hits and an RBI for the D-backs, who have won four of their first five games this season.
Patrick Corbin (1-0) allowed two runs on eight hits over six innings to earn the win.
"Corbin was struggling early on, but kept them from adding on," Arizona manager Kirk Gibson said. "It is a good ballpark to hit in. We got some good pitches to hit and didn't miss them."
Jean Segura went 3-for-4 with an RBI and Alex Gonzalez also drove in a run for the Brewers, who have dropped four straight after an Opening Day victory.
Mike Fiers (0-1) allowed six runs on nine hits -- including two homers -- over five frames to absorb the loss.
"Commanding the ball is his big problem," Brewers manager Ron Roenicke said of Fiers. "That could be from a lack of confidence, or getting out of rhythm with your delivery. Or both. We need to find out what the answer is to get him back on track."
Hill plated Martin Prado with a double in the first inning, but Gonzalez brought Norichika Aoki home after a sacrifice fly in the home half, tying the game 1-1.
Segura's RBI double in the second plated Khris Davis, but the Diamondbacks added three runs in fourth and two in the fifth to take a 6-2 lead.
Goldschmidt opened the fourth with a double and Kubel followed with his first homer of the season. Later in the inning with runners on first and second, Parra ripped a base hit to left to score Eric Chavez.
Montero drew a one-out walk in the fifth and Goldschmidt followed with a two- run blast to left center. It was his second homer of the season.
Goldschmidt scored on a throwing error by Segura in the seventh, and Erick Hinske plated Chavez with a single to make it 8-2.
Hill's solo shot in the eighth accounted for the final margin.
