Prediction

I like the Over in this one. The Giants are a low-scoring team, but have produced seven runs in each of their last two games and just allowed Colorado to score 13 against them. Whisenhunt has been awful since entering the rotation in June and boasts a 9.26 ERA on the road. Griffin has struggled of late, allowing 12 runs over his last three starts, including five home runs allowed. I think we’ll see some runs on Tuesday night.

Pick: OVER 8 -110
