Don't look now but San Diego has won five straight games and enters a crucial four game home weekend series against NL West rival San Francisco. For the Giants, Robbie Ray is a shell of himself away from home: 3-5 with a 4.35 ERA vs. 6-1 with a 2.22 ERA at Oracle Park. Look out for the middle of the Padres' batting order against Ray: Manny Machado, Ty France, and Luis Rengifo are a combined 19 of 48 (.396) with 7 home runs against the left hander. Look for San Diego's top notch bullpen to throw at least four innings in relief of J.P. Sears and lead the Padres to another home victory.
