Stephen Strasburg of the Nationals will be going for his eighth straight win Saturday. He'll face a Diamondbacks team that struggled to muster one hit in Friday's series opener. That's not a good sign as Strasburg has allowed one run or fewer in four of his last five starts. Look for the Nationals' bats to deliver early and often and for Washington to deliver as a steep road favorite.

Washington should not be this big of a favorite. Even though Stephen Strasburg has won seven consecutive starts, Arizona starter Robbie Ray is coming off a strong July, with quality starts in four of five outings. My model says that the Diamondbacks win this game almost 50 percent of the time, so you're getting great value with Arizona at plus-money. Take the D-backs.

Stephen Strasburg is 14-4 with a 3.26 ERA and he went 5-0 with a 1.14 ERA in July, as well as winning seven straight starts. Robbie Ray is 9-7 with a 3.91 ERA and he gave up five earned runs in his only start against the Nationals this season. In his career, Ray is 0-5 with a 6.52 ERA against the Nationals. Stephen Strasburg is 7-2 with a 3.06 ERA on the road and he is 4-2 with a 3.55 ERA in his career at Chase Field. The Nats have the fourth highest OPS in the league against lefties, ride the hot Strasburg.
