MILWAUKEE (AP) -- Ryan Braun and Travis Shaw hit back-to-back homers, helping the Milwaukee Brewers to an 8-0 victory over the Miami Marlins on Friday night.

   It was the fourth consecutive win for Milwaukee, which has outscored Miami 20-3 in the first two games of the series.

   Shaw and Christian Yelich each reached base four times, while Lorenzo Cain and Eric Thames were on base three times apiece. Shaw has been on base eight times (four walks, three hits and hit by pitch) in the first two games against the Marlins.

   Jhoulys Chacin (1-1) picked up his first win since signing with the Brewers as a free agent during the offseason. The right-hander pitched six innings, scattering four hits and three walks while striking out five.

   Miami starter Trevor Richards (0-2) lasted only 3 2/3 innings, giving up six runs on five hits and six walks while striking out five.

   Leading 1-0 after three innings, Milwaukee scored five runs in the fourth. Yelich tripled home Cain to make it 2-0. Braun hit the next pitch for a two-run homer, his fifth, and Shaw hit Richards' next pitch for his third homer to make it 5-0.

   Milwaukee shortstop Orlando Arcia was helped off the field after twisting his right ankle attempting to get back to first base after singling in the eighth.

   The Marlins, losers of five of six games, have struggled to throw strikes the first two games of the series. Miami pitchers have walked 15, hit two batters and thrown three wild pitches.

   Milwaukee pitchers have thrown shutouts in three of the last four games, beating Cincinnati by identical 2-0 scores on Tuesday and Wednesday.
