San Francisco Giants over Arizona Diamondbacks: Given the venue we will rate the offenses equal. This line is lower than it should be in part because of the run differential of these 2 teams. Ariz should have a better record SF should have a worse record. However these teams are presently tied in the standings and with a med adv in starting pitching and Ariz best hotter Peralta out more than makes up for the run differential. We also have a small adv in the bullpen giving us excellent value given I have this game at 1.39.
