SAN FRANCISCO -- Madison Bumgarner homered and doubled, struck out 14 and pitched a three-hitter as the San Francisco Giants beat Washington 5-0 Sunday, the Nationals' sixth straight loss.
Hunter Pence also homered as the playoff-contending Giants finished off a four-game sweep.
Washington matched its longest skid of the season. A popular pick before opening day to win the World Series, the Nationals fell below .500 at 58-59.
Bumgarner (14-6) held the Nats hitless into the fifth inning. The World Series MVP matched his career high for strikeouts while pitching his first shutout of the year and fourth overall in the regular season.
