Diamondbacks vs Giants Prediction
The Diamondbacks are 6-1 in their last 7 meetings against the Giants but are 1-2 in their last 3 visits in San Francisco. They swept their previous series at home by 3-0 wins and a combined 23-8 score.
In this Diamondbacks vs Giants Prediction, the Giants are coming as -140 home favorites. The Giants are coming off back-to-back wins where they scored a combined 18 runs and their offense is starting to get hot. They also have the pitching edge in this game as Landen Roupp goes up against a struggling Merrill Kelly for the Dbacks and the Giants have superior bullpen, ranking 7th in the league. I also like the fact that the Giants got swept in their previous series against the Dbacks, so this is a nice revenge spot. Take the Giants on the moneyline in this one.
