GUNIT - I agree with you that looking at the game, I like the over more. Can't trust the bravos to win the game much less lay -170. Wouldn't touch either though as these two teams are so unpredictable.
If however I were to lay 70% of my bankroll on a side tomorrow it would be on Arizona at about the same odds. At least you know you have the best pitcher in baseball right now, the hotter team, the team playing at home with a better record, a team that can score runs in bunches. And if you lose you won't second guess yourself by taking the best pitcher in all of baseball at the moment.
Best of luck whatever you do.
