The set-up: Here's a matchup where I don't think that the home field advantage can be overlooked as a very real deciding factor. The visitors hand the ball to Jason Vargas, while the home side counters with Zac Gallen.

The pitchers: Vargas (6-5, 3.93 ERA) gave up two runs off five hits over six innings in a no-decision to the White Sox on Friday.

Gallen (1-3, 2.72) started seven games for Miami before getting traded and I think he's going to respond in his first start for his new club. Gallen would go on to allow 25 hits and post 43 strikeouts while walking 18 over 36 1/3's innings of work for the Fish.

The pick: Note as well that Gallen has pitched seven innings in each of his last two starts. And note that while Vargas is 3-2 with a 2.92 ERA in all in home situations this year, he's just 3-3 with a 5.03 ERA on the road. All things considered, a great price on the home side here. Lay it.
