Max Kepler homered, Jose Berrios threw six shutout innings to outduel Yu Darvish and the Minnesota Twins beat the Chicago Cubs 4-0 on Sunday night.
Kepler had three hits and Josh Donaldson added two for the Twins, who took two of three from the NL Central-leading Cubs.
After winning the AL Central last year, Minnesota clinched its second straight postseason berth on Saturday and trails the Chicago White Sox by two games in the division.
The Cubs scored just two runs in the series and maintain a 3 1/2-game lead over St. Louis in the NL Central. Chicago had won five of six.
The Cubs loaded the bases in the ninth on a passed ball, a hit batter and a walk against Sergio Romo, who struck out Nico Hoerner to end the game.
Darvish (7-3), an NL Cy Young candidate, allowed a season-high four runs and nine hits in his quest to become the NL's first eight-game winner. He struck out nine and walked one, ending a streak of nine consecutive quality starts. Darvish was 5-2 with a 2.16 ERA in his previous eight starts at Wrigley.
Jon Lester (2-2, 4.91) takes the mound Monday to open a four-game series at Pittsburgh. He is 0-2 with a 6.82 ERA in his last seven starts. The Pirates will start RHP JT Brubaker (1-2, 4.79).
