The first half of Sunday's game was the best the Eagles have played in a while, ending in a 4-yard Carson Wentz touchdown pass to Darren Sproles, which gave the Eagles a 13-7 halftime lead.
It was their first halftime lead since the Atlanta game, Nov. 13, which perhaps not coincidentally was the last time they won.
They could have built a more substantial lead, but three previous long drives netted only a pair of Caleb Sturgis field goals, sandwiched around an end-zone interception.
The Redskins put together only one drive, but it ended in a 22-yard Robert Kelley touchdown run through an Eagles defense that had been doing an excellent job against the run.
Fletcher Cox managed the team's first sack since the Seattle game, his first since Detroit, back on Oct. 9.
Wentz was excellent in the drive just before the half, which covered 77 yards in 13 plays. He finished the half 18 for 24 for 177 yards, the touchdown and the pick, a 91.8 passer rating.
Zach Ertz caught 5 passes for 65 yards. The Eagles lost running back Wendell Smallwood to a knee injury, so with Kenjon Barner inactive, Nelson Agholor returned the kickoff after the Washington touchdown.
Washington's Kirk Cousins was 6 for 9 for 60 yards.
