Jackson Chourio hit a two-run home run, Frankie Montas pitched six scoreless innings, and the Milwaukee Brewers beat the San Francisco Giants 3-0 on Thursday night to take another step toward clinching the NL Central. The Brewers, who hold a nine-game lead over Chicago in the division, took two of three from the Giants and reduced their magic number to seven. The game was scoreless until Milwaukee's Willy Adames reached base with a walk in the seventh and rounded the bases on three Camilo Doval (0-1) wild pitches.
