Diamondbacks vs Giants Prediction

In their 13 meetings last season, the Dbacks led the Giants 7-6 wins. In their two series in San Francisco, the Giants led the Dbacks 4-3 wins. Over is 8-2-2 in their last 12 meetings, and 4-1-1 in their last 6 meetings in San Francisco.

In this Diamondbacks vs Giants Prediction, both teams are coming at a pickem price of -110. The Giants have a better record, and have been very strong at home, while the Dbacks are just above average on the road.  Both teams are not in good form lately, and both pitchers are shaky, so i see no value on either side. Both pitchers have a combined 8.59 ERA this season, and both teams have been hitting righties very good, averaging 5.3 and 5.1 runs per game against them. The total is set at 7.5 runs, and I expect more than 8 runs in this game, as both offenses can explode any given time. Take the over 7.5 runs.
