WASHINGTON (AP) DJ LeMahieu hit a tiebreaking two-run single off Drew Storen with two out in the eighth inning, sending the Colorado Rockies to a 6-4 victory over the Washington Nationals on Sunday.

Carlos Gonzalez hit two solo shots and Daniel Descalso also went deep for Colorado, which has won three of four. Gonzalez, who hit a grand slam against Storen on Friday night, is batting .394 with 15 homers and 34 RBIs in his last 27 games.

John Axford (4-5) got five outs for the win, and Tommy Kahnle worked out of a bases-loaded jam in the ninth while recording his second save.

Ryan Zimmerman homered twice for the Nationals, who remained 1 1/2 games behind the NL East-leading Mets. Max Scherzer struck out 10 in six innings, but allowed four runs and eight hits.

Washington tied it at 4 in the sixth when Jayson Werth scored on Michael Taylor's one-out bouncer to third. Nolan Arenado's throw home pulled catcher Michael McKenry away from the plate.

But the Rockies bounced back in the eighth. Ben Paulsen reached on a leadoff single and McKenry was hit by a pitch. Following a sacrifice and a fielder's choice, LeMahieu drove in McKenry and Kyle Parker with a single to left.

Storen (2-2), who lost the closer job when Jonathan Papelbon was obtained in a July 28 trade with Philadelphia, had a 1.52 ERA coming into the series. Sunday's outing left him with a 2.70 ERA.

Rockies starter Yohan Flande allowed three runs and six hits in 4 2-3 innings.

Zimmerman and Jayson Werth connected on consecutive pitches in the second to give Washington back-to-back homers for the first time this year. Zimmerman's homer in the third was his ninth of the year and fourth in 42 at-bats since being activated from the disabled list following a foot injury.

MR. EXTRA BASE

Eight of Zimmerman's 13 hits since he returned from the DL have gone for extra bases (five doubles, three homers).

TRAINER'S ROOM

Rockies: With a day game after a night game in the midst of 10 straight games without an off day, manager Walt Weiss rested C Nick Hundley and LeMahieu in favor of McKenry and Descalso. LeMahieu entered in the seventh.

Nationals: RHP Aaron Barrett's option was voided. He was placed on the 15-day DL retroactive to Aug. 6 with a sprained right elbow.

UP NEXT

Nationals: LHP Gio Gonzalez (8-4, 3.75 ERA) gets the ball for Washington on Monday night in the opener of a three-game series in Los Angeles against the NL West-leading Dodgers. Gonzalez is 2-0 with a 2.61 ERA in four starts since the All-Star break.
