Milwaukee plated two runs in the bottom of the ninth against Cubs reliever Hector Rondon, making things interesting, but a fly-out off the bat of pinch-hitter Logan Schafer ended the contest, sending Chicago to a four-game sweep of the Brewers.
Chicago (57-47) moved to a season-high 10 games over .500 with the win Sunday, pulling them into a tie with the San Francisco Giants for the second wild card spot in the National League.
One of the bigger storylines from the win surrounded Chicago rookie Kris Bryant, who, with the Cubs leading 3-1, singled to center field to make it a three-run lead.
