Nationals 4, Diamondbacks 1
BOX SCORE
WASHINGTON -- Jayson Werth hit a three-run homer, Ross Detwiler took a four-hitter into the seventh inning and the Washington Nationals beat Arizona 4-1 Monday night to extend the Diamondbacks' losing streak to a season-high six games.

Henry Blanco homered for the Diamondbacks, who have scored only seven runs in their last six games. Mired in its longest skid since a seven-game run in July 2010, Arizona now leads second-place San Francisco by just one game in the NL West.

Werth has had few shining moments this season after signing a 126 million, seven-year deal in December. But he carried the Nationals in this one, scoring a second-inning run before delivering the decisive blow in the fourth against Joe Saunders (8-11).

Detwiler, meanwhile, was dominant against the punchless Diamondbacks. The left-hander came in with a career record of 3-12, but allowed only one runner past second base until Blanco hit a drive into the left-field seats with two outs in the seventh.

Blanco's homer, on a 3-2 pitch, enabled Arizona to avoid a second straight shutout loss. Blanco has six homers and nine RBIs this year.

Detwiler (2-3) gave up one run and six hits in 6 2-3 innings. He walked one and struck out three to break a three-game losing streak.

Drew Storen, the third Washington reliever, worked the ninth to secure his 34th save and seal the Nationals' fifth win in seven games.
