The four-game visit with the Cubs became a preview of how manager Mike Shildt and pitching coach Mike Maddux could set their bullpen for a postseason series and the roles they have in mind for their lefties. With two switch-hitters and lefthanded-hitting Jason Heyward due up in the ninth, Miller got the late-inning, high-leverage assignment Sunday and got his sixth save of the season in the 3-2 victory. Webb drew the one-batter, one-out duty in the eighth, retiring lefthanded-batter Kyle Schwarber with runners at the corners to keep the Cubs’ lead to a run and later get the win.
