The MLB Power System Play is on San Diego at 9:40 eastern. The Padres fit a perfect Power system that plays on Division home favorites off a road favored loss if they scored less than 4 runs and are taking on an opponent like Arizona that comes in off a home dog win that scored 6+ runs. These teams are perfect since 2004. The Padres are 15-7 off a loss and have won 8 of 11 here vs Arizona. The Diamondbacks are 11-54 on the road if the total is 7 to 8.5 and 5 of 7 off a win. SD has won 8 of the last 10 with Darvish. Davies has lost 3 of 4 on the road. Look for San Diego to take the opener.
