William Contreras' sacrifice fly in the first plated Chourio to get the Brewers on the board.

In the third, Adames hit a leadoff double and scored one batter later on Lee's double. After an Eldridge walk, Chapman's grounder up the middle knocked in Lee.

Milwaukee pulled within 6-3 on Chourio's two-run homer in the fifth.

The Giants opened the seventh with six straight hits and took a 12-3 lead. Lee, Eldridge and Chapman singled and scored on Haase's grand slam to center.

In the ninth, Blake Perkins coaxed an RBI walk, Sal Frelick scored Gary Sanchez on a fielder's choice and Luis Rengifo had an RBI single. But Hamilton flied out to the warning track with two runners on to end it.

Crow (0-1) surrendered six runs on nine hits, walked two and struck out two in 2 1/3 innings. Sam Hentges (1-0) picked up the win with two-thirds of a scoreless inning and Caleb Kilian earned his fourth save.

Milwaukee relievers DL Hall (left subscapular or pectoral discomfort) and Grant Anderson (right forearm contusion) both exited with injuries.
