Stephen Nover's MLB Game of Week - 67% Streak!
(MLB) Colorado vs. Arizona,
Money Line: 103.00 Colorado (Away)
Result: Loss
Colorado had held Arizona's number winning eight in a row against the Diamondbacks - until Friday night. The Rockies couldn't do anything against Zach Greinke in an 8-0 loss.

Look for the Rockies, though, to start a new win streak against the Diamondbacks in a pitching matchup of Jon Gray versus Robbie Ray.

Gray has always had a high ceiling and he's been pitching much better with a 2.90 ERA in his last nine appearances spanning 49 2/3 innings. Gray has 52 strikeouts during this span. Colorado is 7-1 in his past eight starts. Gray is 1-0 with a 2.38 ERA in two starts versus Arizona this season, including holding the Diamondbacks to one earned run in six innings at Chase Field on June 19.

Gary won't have to worry about injured David Peralta, the Diamondbacks' third-best hitter.

Ray hasn't pitched well for more than a month giving up three earned runs or more in six of his last seven starts. His ERA has gone from 3.26 to 4.10 during this time frame.The lefty has a 5.49 ERA in 15 career starts versus the Rockies. Nolan Arenado, Charlie Blackmon and Trevor Story have a combined .388 batting average against Ray with 10 homers in 103 at bats.

The Rockies rank in the top four in the National League against lefthanded pitching in a number of categories, including batting average, slugging percentage and OPS.
