Andrew Stevenson and Wilmer Difo hit back-to-back homers in a five-run sixth inning, and Ryan Zimmerman added a solo shot in the seventh as the Washington Nationals defeated the Philadelphia Phillies 10-4 in a rain-delayed game at Nationals Park on Tuesday night.

The Nationals made a few surprising moves earlier in the day, trading away Matt Adams and Daniel Murphy, but they scored a somewhat surprising comeback victory in this game.

Washington starter Tanner Roark lined an RBI double before the rains stopped play after the top of the third. He threw three scoreless innings while going for a sixth consecutive win but did not come back out after the 1-hour, 42-minute rain delay.

Phillies starter Vince Velasquez actually did come back and pitched two more innings, going four overall and giving up one run on three hits. He struck out three with one walk.

Jimmy Cordero (1-0), a former Phillies farmhand, earned his first major-league win thanks to a scoreless sixth inning.

Victor Arano (1-2) took loss for the Phillies after giving up four of the five runs in the sixth.

Washington grabbed the lead before the rain when Roark came through with the RBI double for a 1-0 advantage. That held up until a wild sixth inning where the Phillies scored four times and Washington came back with five and a 6-4 lead.

Roman Quinn started it for Philadelphia with his first career homer, a solo shot. Asdrubal Cabrera (RBI single), Carlos Santana (RBI single) and Maikel Franco (groundout) each drove in a run for a 4-1 lead.

Then, in the bottom of the inning, Matt Wieters delivered an RBI single followed by a pinch-hit two-run homer from Stevenson -- also his first in the majors.

Difo came up next and crushed a homer into the second deck for a 5-4 lead, which knocked out Arano. Bryce Harper later added an RBI double that scored Trea Turner from first.

Zimmerman added his solo shot an inning later which made it 7-4. Anthony Rendon (RBI double) and Wieters (two-run single, three RBIs overall) helped the Nationals stretch the lead to 10-4 in the eighth.
