Manny Machado knocked in three runs and Yu Darvish fired five scoreless innings in his return from the injured list as the San Diego Padres snapped a five-game losing streak with a 6-4 win over the visiting Cincinnati Reds on Tuesday night. After throwing 50 of his 70 pitches for strikes, Darvish left with a 5-0 lead after San Diego reached Nick Martinez (0-2) for four runs in the bottom of the fifth. The big hit came from Machado, who drilled a three-run double on a high sinker from Martinez to make it 4-0.
