HOUSTON -- Matt Wieters hit a two-run homer, Howie Kendrick had a two-run triple and the Washington Nationals beat Houston for the ninth straight time, 4-3 Tuesday night in a matchup of division leaders.
Washington's winning streak over the Astros dates to 2012. The Nationals have won 13 of 14 against Houston since 2011.
Kendrick's triple tied it in the third before the Astros went back on top with an RBI single by Josh Reddick in the bottom half. Anthony Rendon doubled with two outs in the fourth before the homer by Wieters, which landed just to the right of straightaway center field, gave the NL East leaders a 4-3 lead.
Tanner Roark (10-8) allowed six hits and two earned runs in 5 2-3 innings and Sean Doolittle pitched a perfect ninth for his 15th save.
Charlie Morton (10-6) gave up four runs in six innings for the AL West-leading Astros.
The Astros threatened in the eighth against Brandon Kintzler when Josh Reddick and Yuli Gurriel hit consecutive singles and the Nationals intentionally walked Carlos Beltran with one out to load the bases. But Max Stassi grounded into a double play to leave Houston trailing.
George Springer led off the Houston first with a single, stole second and scored on a two-out single by Reddick.
Beltran doubled off the wall in left-center field in the second and scored on a single by Derek Fisher.
