In 18th, Giants belted to big 2-0 NLDS lead

Engaging the Washington Nationals in a standoff that was equal parts endurance test and fight for survival, the Giants captured Saturday’s Game 2 of the National League Division Series, 2-1, on Brandon Belt’s tiebreaking home run leading off the 18th inning. San Francisco forged ahead in the best-of-five series, 2-0, and needs one more victory to advance to the next postseason round.
