On Sunday the system play is on the Arizona Diamondbacks.Game 905 at 1:35 eastern.Arizona fits a nice system here that is 29-12.What we want to do is play on road favorites off a road favored loss at -140 or higher that lost by 2 or more runs and scored 2 or less runs,vs an opponent off a home dog win that scored 5+ runs and had 5 + hits.This system has cashed 29 of 41 times.If our opponent left 10 or more on base the system tops out at 8-1.Arizona is 12-4 vs losing teams in the second half and should avoid the sweep here today.In the pitching matchup they have Y.Petit and he has been coming on of late with a 2.95 era over his last 3 starts.Washington counters with J.D.Martin and he has struggled with a 6.97 home era.The Nationals have shown they have not thrown in the towel playing hard for their new manager.However look for the 7 game win streak to end today.For the system play take the Arizona Diamondbacks.bol GC-
