Washington won the first two games in Houston, then Houston returned the favor by taking three straight in D.C. With Wednesday night’s victory, the Nats took two more in Texas.

Houston starter Zack Greinke rolled through the first six innings, allowing just one hit and walking one. But then Washington’s Anthony Rendon smacked a solo homer in the seventh, and Howie Kendrick greeted reliever Will Harris with a two-run shot, giving the Nats a 3-2 lead.

In the eighth, Juan Soto's single scored Adam Eaton, giving the Nats a 4-2 lead.

Eaton then knocked in two runs with a single in the top of the ninth, giving Washington a 6-2 lead.

The Astros had gotten off to a 2-0 start, scoring once in the bottom of the second on Yuli Gurriel's home run off Washington starter Max Scherzer, and again in the bottom of the fifth when Carlos Correa's two-out RBI single eluded diving Washington third baseman Rendon.

The Nationals franchise moved to Washington in 2005 after starting as the Montreal Expos in 1969. Prior to the Nationals' arrival in D.C., the nation's capital had gone without Major League Baseball for more than 30 years.

The first version of the Washington Senators became the Minnesota Twins in 1961 after winning three American League pennants and one World Series title. The new version of the Senators, started in 1961, became the Texas Rangers in 1972. That club never won a title in D.C.
