Leo Rivas lined a game-ending single that scored Dylan Moore in the bottom of the 10th inning, and the Seattle Mariners rallied late for a 6-5 win over the San Francisco Giants on Friday night. The first game under new manager Dan Wilson was memorable even if it took the Mariners until the eighth inning before their bats warmed up. Seattle scored four times in the eighth inning to pull even at 5-5, then saw Rivas come through in the 10th.
