Luis Matos hit a three-run home run and the San Francisco Giants beat the Miami Marlins 4-2 on Sunday. After Wilmer Flores knocked in a run with a groundout in the second inning, Matos connected on a 2-0 changeup from Ryan Weathers (1-1) in the third that traveled 390 feet to left-center and gave the Giants a 4-0 lead. San Francisco did not score after that, marking the 14th straight games the Giants have failed to score more than four runs.
