Russell added two doubles and two RBIs, and the Cubs had production up and down the lineup in their 16-hit attack.
The only damage the Marlins mustered off Arrieta was Marcell Ozuna's home run to open the second inning. The no-doubt drive to left was the Miami left fielder's 20th of the season.
The Cubs wore down Jeff Locke in the second inning, inducing 34 pitches from the Marlins' left-hander and scoring twice. Arrieta had an RBI infield single in the inning. And in the fourth, Bryant blasted his three-run homer on a 3-1 changeup from Locke, breaking open a four-run lead.
