I have this one marked much higher. I don't believe the oddsmaker is giving the Rockies and their starting pitcher, Antonio Senzatela, enough respect here.

The right-handed Senzatela has proven he can pitch well at Coors Field. Colorado is 10-3 during the last 13 games he's pitched there. He has a 3.12 ERA in this span. The Nationals have lost 25 of the last 36 games they've gone against a righty starter.

Washington starter Aaron Sanchez hasn't been good for years - and he's not good this season with a 6.75 ERA.
