The set-up: This series features a couple of competitive match-ups on the mound and this is one of them. However, I think that Patrick Corbin and the home side have the advantage, making this a price that I can live with paying. The visitors go with Felix Pena on the mound.

The pitchers: Pena is so far 1-3 with a 4.35 ERA. He most recently gave up one run off two hits with four walks while striking out seven over six innings in a victory over San Diego on Wednesday. Pena has looked solid of late, but I think he's going to struggle in this difficult venue.

Corbin is so far 10-4 with a 3.18 ERA. He most recently gave up three runs off six hits with no walks while striking out seven over seven innings in a win over the Rangers on Tuesday. It was his third-straight quality outing and to go along with his solid ERA, he also sports a sharp 1.03 WHIP and 11.0 K/9.

The pick: Take it for what you will as well but Arizona is 7-2 in its last nine night home games in which its a favorite in the -125 to -200 range. I like Corbin to find a way to get the job done at home, play on Arizona.
