On Friday the National League Power system play is on the Over in the Arizona at San Francisco game. Rotation numbers 963/964 at 10:15 eastern. This game fits a powerful system that is perfect and plays the over for when home teams like the Giants take to the road off a road dog loss by 5 or more runs, if they scored 2 or less runs and are taking on an opponent that comes in off a home favored loss and also scored 2 or less runs while having no more than one error in that loss. These games average nearly 12 runs per game. In the series here 7 of the last 9 have flown over the total. Arizona has gone over the last 4 times on the road off a home favored loss. Ian Kennedy for Arizona makes the start and he has gone over in 6 straight road July starts and 5 of his last 6 on the road overall. He will take on Chad Gaudin, has made just a handful of starts and is facing Arizona for the first time since 2009. Look for this game to go over the total tonight.
