The set-up: This series features a couple of competitive match-ups on the mound and this is one of them. However, I don't expect Zack Greinke to have a letdown here, as he's consistently been at this best at home. The visitors hand the ball to Mike Leake in this one.

The teams: Leake is so far 8-7 with a 3.90 ERA. Leake missed his last start due to an illness and while he's been decent overall this year, one has to wonder if the veteran has completely recovered at this point?

Greinke is so far 12-8 with a 3.06 ERA. He most recently gave up three runs with seven strikeouts over six innings in a no-decision to the Padres on Sunday. Greinke continues to grind out consistent results, along with his very respectable ERA he also has a sharp 165:32 K/BB.

The pick: As mentioned off the top, Greinke has been a lot better at home this year (5-3, 2.34) than on the road (7-5, 3.76). And take it for what you will, but Arizona is 7-2 in its last nine home day games in which it's a favorite in the -150 to -200 range. No upsets here, lay the price.
