The Colorado Rockies have dropped eight-of-ten games against the Arizona Diamondbacks this season and are 8-22 since the start of August. Arizona has also struggled in the second-half of the season with a 21-33 mark since the start of July, but did enough legwork in the first three months to keep themselves in contention and currently sit in a three-way tie for the final Wild Card spot alongside the Miami Marlins and San Francisco Giants.
For the Rockies, it will be yet another opportunity to play spoiler. They will send Peter Lambert to the mound in game one-of-three against the Snakes.
