Brewers vs. Rays trading preview

The Brewers' bats exploded during two big innings in Tuesday's 10-1 win. Milwaukee scored two runs in the third inning before adding eight runs on eight hits in the fifth. Jackson Chourio and Christian Yelich scored on an infield single by Brice Turang to start the fifth inning surge, which was capped off by Chourio's RBI double scoring David Hamlilton.

Turang finished the game with three hits and two RBIs in five at-bats. Starter Robert Gasser earned the win pitching six scoreless innings, recording three strikeouts and allowing one hit and one walk. Milwaukee can clinch its first World Series title in franchise history, having previously made one appearance, losing to the St. Louis Cardinals as a member of the American League, in 1982.
