However, the Brewers tied it in the seventh before Addison Russell scored the go-ahead run in the bottom half of the inning on an error by Brewer shortstop Eric Sogard. Brandon Morrow earned his sixth save of the season by pitching a perfect ninth inning in the 3–2 win. The win moved the Cubs three games over.500 for the first time on the season. Kris Bryant missed his fourth straight game.

Addison Russell drove in a run in during the sixth as the Cubs only needed one, shutting out the Brewers again, this time 2–0. The Cubs swept the four-game series from the Brewers and beat the Brewers for the seventh time in eight games to start the season. The win moved the Cubs to 15–10 on the season and only half a game out of first place. In the four-game series, the Cubs only allowed two runs, only one earned, the first time they had allowed only two runs in a four-game series since 1919.
• April 30 – Anthony Rizzo drove in the winning run with a groundout in the sixth inning following a Kris Bryant triple. The Cub pitching was again spectacular, allowing only two runs, none earned, in the 3–2 win over the Rockies at Wrigley Field. Luke Farrell got his first career win in relief and Steve Cishek earned his first save as a Cub as Brandon Morrow had the night off. Addison Russell and Albert Almora Jr. each drove in a run as the Cubs won their fifth straight and moved into sole possession of first place in the NL Central.

• May 20 – In the final game of the four-game series, the Cubs fell behind 1–0 in the first as Yu Darvish struggled mightily in the inning, but only allowed the one run in the inning.

• May 27 – After placing Yu Darvish on the DL, the Cubs moved Tyler Chatwood to their ESPN Sunday Night Baseball start against the Giants. Chatwood continued his season-long struggles, walking five in 2.2 innings before being removed from the game. The bullpen tossed 6.1 scoreless innings of relief and Javier Báez hit a go-ahead three-run home run in the fourth to give the Cubs the 8–3 win.
• May 28 – After a night game the night before, the Cubs traveled to Pittsburgh to take on the Pirates at 1:35 pm local time.

The Cub bullpen pitched 3.1 innings of perfect relief as the Cub offense came alive later in the game to blow out the Pirates 7–0. Anthony Rizzo homered in the second and drove in three runs while Addison Russell hit a two-run, pinch-hit home run in the seventh to extend the Cub lead. In the eighth inning with the bases loaded, Rizzo took out Pirate catcher Elías Díaz who was attempting to turn a double play. The takeout slide by Rizzo forced Díaz's throw into right field and allowed two more runs to score. Pirate manager Clint Hurdle was thrown out for arguing that it was an illegal slide after the play was reviewed. Both Díaz and Hurdle stated after the game that they thought the slide was dirty.

The Cub bullpen allowed two runs in the ninth before Brandon Morrow got his 12 save of the season as the Cubs won 8–6 and moved a season-high seven games over.500.
• May 30 – Looking to complete the sweep of the Pirates, Kyle Hendricks gave up two runs on seven hits in five innings.

Leaving 11 runners on base in the game, the Cubs fell 2–1.
• May 31 – José Quintana pitched six scoreless innings while Ben Zobrist hit a two-run home run as the Cubs visited the New York Mets. The Cub bullpen gave up a solo home run, but Brandon Morrow got his 13th save as the Cubs won 5–1.

• June 5 – After an off day, the Cubs returned home to welcome the Philadelphia Phillies and former Cub pitcher Jake Arrieta to Wrigley Field. Though Arrieta was not scheduled to pitch in the series, the Cubs gave him a video tribute between innings and the crowd cheered him as he came out of the dugout to acknowledge the crowd. In the game, the Cub offense was stymied by Phillies starter Zach Eflin, failing to score until the eighth inning. Meanwhile, Kyle Hendricks struggled for the Cubs, giving up five runs in five innings of work as the Cubs fell 6–1.

• June 9 – The Cubs managed only two runs on six hits, scoring on a groundout by Ben Zobrist and sacrifice fly from Anthony Rizzo in the first inning. However, Jon Lester pitched seven strong innings while giving up only one hit. The Cub bullpen finished the game for Lester without allowing a baserunner as the Cubs retired the last 19 Pirates in the game to win 2–0. The win moved the Cubs 13 games over.500, but they remained half a game behind the Brewers in the division.
• June 10 – Kyle Hendricks pitched well, but was lifted for a pinch hitter in the fifth inning trailing 1–0. Taking Hendricks out early backfired as the Cub bullpen fell apart, allowing five runs in the sixth as the Cubs lost to the Pirates 7–1. The loss ended the Cubs four game winning streak.
• June 11 – The following day, the Cubs traveled to Milwaukee to face the division-leading Brewers. José Quintana pitched well, giving up two runs, but left the game with the Cubs trailing 2–1.

• June 16 – Addison Russell and Jason Heyward each homered against the Cardinals as Kyle Hendricks pitched six innings and allowed three runs. Brandon Morrow, pitching for the first time in over a week, struggled, giving up two hits in the ninth, but earned the save as the Cubs won 6–3.
