Kevin Newman tied the game with a two-run, ninth-inning single, and Bryan Reynolds followed with an RBI single as the Pittsburgh Pirates took advantage of a depleted San Francisco Giants bullpen to rally for a 6-4 victory on Monday in the opener of a four-game series. The four-run uprising came after Giants ace Madison Bumgarner left with a 4-2 lead after seven innings. A single by Kevin Kramer, a walk to Josh Bell and a single by Elias Diaz loaded the bases for the Pirates with one out in the ninth, setting the stage for Newman's game-tying hit off the Giants' third pitcher of the inning, Jandel Gustave.
