MILWAUKEE -- Orlando Arcia hit a three-run homer and Ryan Braun belted his sixth career grand slam as the Milwaukee Brewers scored eight runs in the second inning and held on for a 9-6 victory over the Philadelphia Phillies on Friday night at Miller Park.

The second-inning explosion bailed out Zach Davies (11-4), who gave up six runs (five earned), seven hits and five walks while striking out six in 5 1/3 innings.

Phillies starter Nick Pivetta (2-5) went five innings and allowed a season-high nine runs with seven hits, three walks and five strikeouts.

Maikel Franco finished with four hits and Odrubel Herrera hit his sixth home run of the season for Philadelphia, which has lost six of its last seven games.

With Pivetta staked to an early 2-0 lead, he struck out the first four Brewers batters before Domingo Santana's one-out double in the second.

Pivetta allowed seven consecutive batters to reach, with Arcia clearing the bases along the way with a three-run homer -- to bring up Braun with the bases loaded.

Braun crushed Pivetta's first offering to straight-away center for his 11th home run of the season and his sixth career grand slam, giving the Brewers an 8-2 lead.

Philadelphia got two runs back in the fifth when Maikel Franco singled to right center for his second hit of the day.

Milwaukee made it 9-4 in the bottom of the inning on a sac fly by Manny Pina.

The Phillies got within three in the sixth on Herrera's two-run shot off Davies.

Corey Knebel worked a scoreless ninth for his 15th save of the season.
