Zach Greinke, who is 10-4 with a 2.95 ERA this season, has won two of his last three starts, and owns a 2.25 ERA over that span. The Diamondbacks have the third best OPS (.846) in the majors against lefties, and Brewers southpaw Gio Gonzalez makes his first start in the majors since returning from the IL with shoulder inflammation. That's a great combination and I'll back the Diamondback here at home on Saturday night.
