It has been awhile, since the last dog series play, but there is potential for one starting on Friday.
Rockies (+100) vs. Padres
Rockies are 23-21 at home this year and Padres are 18-24 on the road. Rockies also 23-20 last 3 years vs Padres and 11-10 at home.
Keep an eye on Game 2 line though as I am not sure that Colorado will be a dog for all 3 games. Saturday's odds should be up around 5pm et so there is plenty of time to stay away from the game if the Rockies are favored for either of the first 2 games of the series.
