HOUSTON (AP) — Riley Adams hit a tiebreaking solo homer in the seventh inning to lift the Washington Nationals to a 2-1 win over the Houston Astros on Monday night.

The game was tied 1-all with two outs in the seventh when Adams connected off Bryan King (3-2) on his 348-foot shot to the seats in right field to put Washington on top.

Christian Walker doubled to lead off the bottom of the inning and Jacob Melton walked. But Yainer Diaz grounded into a double play before Luis García struck out Mauricio Dubón to end the threat.

Konnor Pilkington (2-0) got the last two outs of the sixth for the win and Kyle Finnegan struck out one in the ninth for his 20th save.

The Astros have dropped a season-high five straight games after being swept in a four-game series by the Athletics this weekend. The AL West leaders have dropped 10 of their last 11 home games and managed just one run for a third straight game.

Nationals’ starter Brad Lord retired the first 14 batters before Diaz walked with two outs in the fifth. Dubón followed with a double on a line drive to left field that scored Diaz and put Houston up 1-0.

There were two outs in the sixth when Framber Valdez walked Josh Bell. Nathaniel Lowe’s double to the right field corner scored Bell and tied the game at 1.

Valdez allowed three hits and a run while tying a season high with 12 strikeouts in six innings to become the 10th pitcher in franchise history to reach 1,000 career strikeouts (1,007). Houston's bullpen struck out seven more as the team tied a season high with 19 strikeouts.

Washington starter Brad Lord yielded one hit and one run in 5 1/3 innings.
