John Wall had 18 points and 11 assists for Washington, which snapped a three-game winning streak and failed to move over .500 for the first time since it was 6-5 last season.

Bradley Beal had 27 points for the Wizards after missing Friday's game against Brooklyn with a right ankle sprain.

Gordon hit a deep 3 to give Houston an eight-point lead with two minutes remaining and later stretched the lead to 10 with a layup with a little more than a minute left.

Washington had a 53-41 halftime lead, thanks in large part to Houston's eight turnovers and poor shooting from beyond the arc.
