hit his first Major League home run and Buster Posey

Arias and Posey both connected for two-run homers to back up Matt Cain (4-2), who picked up the win despite allowing four runs on 11 hits over seven innings.
Cain did not issue a walk and struck out eight en route to his first win over the Brewers since 2009. He gave way to Sergio Romo and Santiago Casilla, who picked up his 11th save.
Shaun Marcum (2-3) allowed six runs on five hits and struck out five over six innings.
