CHICAGO -- Michael Wacha pitched into the seventh inning for his first win in nearly two months and the St. Louis Cardinals waited out Jake Arrieta before roughing up Chicago's bullpen in a 7-2 victory over the Cubs on Wednesday.
Aledmys Diaz hit a two-run home run, and Matt Carpenter had a two-run double in a five-run sixth after Arrieta (11-2) departed. The Cardinals won their eighth straight road game -- their longest streak since 1982 -- and completed their first three-game sweep at Wrigley Field since 1988.
