Reese McGuire hit a two-run homer and Kyle Tucker hit a solo shot for the Cubs, who won for the second time in their last seven games.
Michael Busch (3-for-5, two runs, RBI) and Dansby Swanson (2-for-5, two runs) also had productive games for Chicago.
After allowing 54 runs in their previous six games, the Cubs shut down the Cardinals.

Ryan Brasier, Michael Fulmer and Porter Hodge worked a scoreless inning each to complete the shutout.
Cardinals starter Erick Fedde (3-7) allowed seven runs on eight hits and two walks in 3 2/3 innings.
Happ hit a home run on the first pitch of the game to give the Cubs an instant lead.
Chicago increased its advantage to 4-0 in the second inning. Swanson led off with a double and scored on Busch's single. After Fedde retired the next two batters, McGuire hit his two-run homer.
Tucker's third-inning homer pushed the Cubs' advantage to 5-0.
The Cubs expanded their lead to 7-0 in the fourth inning. Busch walked, stole second base and moved to third on a flyout to start the rally.
After Matt Shaw walked and stole second base, Happ hit a two-run single. Chicago loaded the bases, but reliever John King got Pete Crow-Armstrong to hit an inning-ending groundout.
Swanson struck out leading off the fifth, but he reached on a wild pitch to start another rally. Busch reached on an infield hit, Nico Hoerner hit a single and Shaw grounded into a run-scoring force play to make it 8-0.
