The Arizona Diamondbacks have played well of late, winning seven of their last 10 overall. They are in Colorado tonight, taking on the last place Rockies who have lost five of their last seven. The visitors appear to have a favorable match-up on the mound, and my money is on Arizona as a small favorite.

Here are my keys to the game:

1. Pitching - Chase Anderson will get the nod for the Diamondbacks, and he's had a stellar season. Anderson (3-1, 2.84 ERA) gave up a pair of runs on seven hits in a win over the Angels in his last start. Prior to that he was working on a no-hitter in San Francisco, until it was broken up with just one hit in the seventh inning in a 1-0 Arizona win. The Rockies counter with Kyle Kendrick, who is win-less with a 6.81 ERA in six home starts.

2. Paul Goldschmidt - The Arizona slugger is batting a major league best .356 with 19 home runs and 55 RBIs. He's hitting .429 with a pair RBIs lifetime versus Kendrick.

3. X-Factor - The Diamondbacks are 6-1 in their last 7 road games vs. a team with a losing record

Selection: This is a play on the Arizona Diamondbacks (10*)
