Manning completed passes of 30, 19 and 11 yards to Burress, who signed a two-year contract extension just hours before the game that will pay him an average of $7 million annually for the next five years.

Burress more than earned his money on the 11-play opening drive. His 11-yard catch got the ball close and Manning scored on a naked rollout one play after a pass-interference penalty gave New York a first-and-goal at the 1.

Carney, signed on Saturday after a knee injury sidelined Lawrence Tynes, kicked a 24-yard field goal to push the lead to 10-0 on the Giants’ second possession. It capped a nine-play, 45-yard drive that featured a bruising 17-yard run by Jacobs on which he bowled over safety LaRon Landry.

The Giants’ defense, which led the league with 53 sacks last season, contributed to the score by forcing Washington to a three-and-out series in Zorn’s debut of the West Coast offense.

Justin Tuck, who replaced Strahan at left end, started the series, with a sack.

Carney’s 25-yarder was set up by a 23-yard pass to Sinorice Moss, Santana’s brother. The drive for the third field goal was highlighted by a 24-yard run by Jacobs that was one step away from a 70-yard touchdown run until Landry got him around the ankle.

Campbell finished 15-of-27 for 133 yards, but he was very ineffective on third down. Washington had the ball for less than 25 minutes.

“The thing that hurt us was not converting those first downs when we had the opportunity,” Zorn said. “We had third-and-6 and we’d made 5. We’d have third-and-9 and make 8½. We’d have third-and-7 and make 6. We just couldn’t get over that line.”

Notes: There was only one turnover, an interception by Redskins cornerback Fred Smoot in the third quarter. ... Redskins middle linebacker London Fletcher had a game-high 17 tackles, 12 solo. ... Cornerback Aaron Ross led the Giants with eight. ...Redskins starting CB Shawn Springs was inactive because of a shin injury. ... DE Jason Taylor had two tackles in his Washington debut. ... Antwaan Randle El has seven catches for 73 yards to lead Washington.
