If there is one team the Rockies can beat on the road it's the Diamondbacks, losers of 50 of their last 58 games and owners of the worst record in baseball.

Colorado has the worst road record in baseball. However, Arizona has the lowest home percentage mark with a 13-27 record at Chase Field.

The pitching matchup and bullpen favor Colorado with Jon Gray opposing Merrill Kelly.

Gray is 5-6 with a 3.89 ERA. He's pitched well in two starts since returning from the injured list giving up two runs in 11 innings with 15 strikeouts.

Kelly is 5-7 with a 4.67 ERA. He is 1-3 with a 7.06 ERA in five career starts versus the Rockies. The Diamondbacks have a terrible bullpen with a 5.23 ERA.

Closer Daniel Bard has solidified Colorado's backend relief corps.
