EAST RUTHERFORD, N.J. – Rookie cornerback Devon Witherson scored on a 97-yard interception return late in the third quarter and the Seattle Seahawks tied a team record with 11 sacks in a 24-3 victory over the struggling and offensively inept New York Giants on Monday night.

Geno Smith threw a 6-yard touchdown pass to DK Metcalf late in the first quarter after a strip-sack by defensive end Mario Edwards Jr. set up a short drive and Keneth Walker III scored on a 1-yard run just before halftime as the Seahawks (3-1) won their third in a row.

A fourth-quarter interception Quandre Diggs set up a field goal by Jason Myers in the fourth quarter as the Seattle improve to 6-0 at MetLife Stadium, including the franchise’s only Super Bowl win.

Bobby Wagner, Jordyn Brooks, Witherspoon and Uchenna Nwosu each had two sacks. Wagner also had 17 tackles.

Graham Gano kicked a 55-yard field goal for the Giants (1-3), who have played one good half in four games this season and have looked nothing like the team that last year made the playoffs for the first time since 2016.

SEAHAWKS: Jamal Adams leaves first game in a year with a concussion

Seattle was clinging to a 14-3 lead late in third quarter when the Giants moved from their 43 to the Seahawks 5. On second and goal, Daniel Jones tried to hit Parris Campbell and the receiver seemed to stumble. Jones’ pass went to Witherspoon, the No. 5 overall pick in the draft, and he scored almost untouched crossing from the right side of the field to the left to make it 21-3.

The Giants’ offense has really struggled the past two games with star running back Saquon Barkley out with high ankle sprain and left tackle Andrew Thomas down with hamstring injury for three games.

The Seahawks didn’t do a lot against the Giants’ defense. The only real drive they had was seven plays, 75 yards just before halftime that was engineered by backup Drew Lock, who replaced Smith after he tweaked a knee and needed X-Rays. The drive included a 51-yard pass to Noah Fant.

Smith, who returned for the second half, finished 13 of 20 for 110 yards. A battered Jones was 27 of 34 for 203 yards. He ran 10 times for 66 yards.

STRANGE START

Seattle’s first offensive play from scrimmage took about five minutes. Walker took a handoff and headed right. Inside linebacker Bobby Okereke broke through and seemingly made a tackle for a 2-yard loss. For a moment everyone on the field stopped.

Walker felt his body never touched the turf and he got up and ran 20 yards downfield, stopped and then to the end zone, where an official ruled touchdown.

There was a long review of the scoring play and videotape showed Walker’s elbow hit the turf. The touchdown call was reversed.
