The Giants turned two interceptions of Kirk Cousins into touchdowns, and Eli Manning was 23-for-31 for 279 yards and two fourth-quarter TD passes, one to Odell Beckham Jr. and the other to Rueben Randle.
The first interception came midway through the first quarter. Prince Amukamara's pickoff gave Giants the ball at the Washington 14. Four plays later, Andre Williams ran it in from the 1 to help make it 9-0.
Earlier, Rashad Jennings set the tone for the Giants almost three minutes into the game when he blocked Tress Way's punt out of the end zone for a safety.
The Giants led 15-6 at halftime. Two Josh Brown field goals were matched by two by the Redskins' Dustin Hopkins.
Brown kicked his third (and longest) FG from 48 yards to make it 18-6 with 7:29 left in the third quarter.
Eight plays after Uani Unga intercepted Cousins, Manning hit Beckham, who easily beat one-on-one coverage for a 30-yard TD as the Giants went up 25-6 with 13:39 to go. Beckham had seven catches for 79 yards.
On fourth-and-goal at the Giants 7 with 9:42 left, Washington running back Matt Jones fumbled out the end zone after being hit by Trevin Wade.
Amukamara appeared to have forced his second takeaway of the night three minutes later when Cousins fumbled, but a review overturned the call.
Cousins threw a 4-yard pass to Chris Thompson with 3:44 left to start a crazy stretch of three TDs in 32 seconds. After Giants coach Tom Coughlin illegally threw the red flag to challenge the TD call (all scoring plays are automatically reviewed) Cousins made it a two-possession game with a two-point pass to Jamison Crowder.
Twenty seconds later, after the Giants recovered an onside kick, Manning hit Randle (seven catches, 116 yards) with a 41-yard TD pass that bounced into hands from the defender's. The Redskins didn't give up, and Rashad Ross returned the kickoff for the game's final score.
The next onside kick slipped through Randle's hands but went out of bounds, and the Giants were able to run the clock down to 1:43 before punting it back to Washington after an incomplete third-down pass coming out of the two-minute warning.
The Giants are off until Sunday Oct. 4, when they visit the Bills in Orchard Park, N.Y. (1 p.m.).
Whew. Finally a game that was rarely in question. The Giants grabbed an early lead, methodically added to it and didn’t squander it this time.
The Redskins turned out to be the perfect foil and elixir for the Giants, a team that has not been able to finish games with a bang. Thursday, they had enough points in the end, plus the Redskins played without the rhythm they displayed in the first two games and turned the ball over three times.
The Giants deployed a stout defense, a democratic approach to offense and a clean, turnover-free effort against a sloppy Redskins team on a picture-perfect evening at MetLife.
There were a few blemishes, such as allowing a 101-yard KO return by Washington’s Rashad Ross in the final minutes after they had taken a 32-14 lead on a 41-yard TD pass from Eli Manning to Rueben Randle, but the Giants kept their focus and begrudgingly closed the Redskins out.
Still, there was nervousness in the air throughout the fourth quarter. The 'Skins played until the final gun, and the Giants, again, did not manage the clock well down the stretch.
As I always say, a win is a win and the Giants needed one badly. It wasn’t pretty, but the standings do not have a column of style point the last time I checked.
