SEATTLE (AP) – Craig Terrill and the Seattle Seahawks delivered the kind of defensive performance they needed with Shaun Alexander and Matt Hasselbeck on the sideline with injuries.

Facing the Oakland Raiders on a stormy night sure helped the cause.

Terrill had three of Seattle’s nine sacks and Seneca Wallace threw a touchdown pass to get his first win as an NFL starter, a 16-0 victory over the Raiders on Monday night.

The Seahawks (5-3) had lost three of four games since Alexander, last year’s league MVP, was sidelined with a broken foot. Hasselbeck, a Pro Bowl quarterback last year, has missed two straight games with a sprained knee ligament, limiting Seattle’s big-strike ability.

But backups Wallace and Maurice Morris did enough to make up for those losses on this night. Wallace went 18-of-30 for 176 yards, including a 22-yard TD pass to Deion Branch in the first quarter, against the Raiders (2-6).

Morris ran for a career-high 138 yards on 30 carries as the Seahawks had a season-high 207 yards on the ground.

While the backups stepped up to help give the defending NFC champion Seahawks a one-game lead over St. Louis in the NFC West, it was the improvement on defense that was most notable.

Seattle had allowed at least 28 points in five successive games for the first time since its first five games in existence in 1976, and held the opposition scoreless in only one of the previous 17 quarters.

But the Seahawks had little trouble shutting down Oakland’s last-ranked offense on a wet and windy night that made it difficult for the offenses. The Raiders gained only 185 yards and failed to score an offensive touchdown for the fifth time in eight games this season.

Andrew Walter was 16-of-35 for 166 yards and couldn’t get the ball deep to Randy Moss against a defense that had been susceptible to the long pass.

Seattle sacked Walter five times in the first quarter, including on three successive plays – the last two by Terrill. The Seahawks added four more in the game, raising Oakland’s NFL worst total to 44 on the season.

The Raiders had won two straight after dropping the first five games of the season but once again proved not to be ready for prime time. They became the first team to be shut out twice in a season on Monday night football, following a 27-0 season-opening loss to San Diego, and have been outscored 53-3 in three prime-time games.

The frustration showed at the end when defensive lineman Tyler Brayton was ejected in the final minutes for kneeing Seattle tight end Jerramy Stevens in the groin.

Oakland’s offensive line was once again overmatched as it has been most of the season. Starting left guard Barry Sims missed the game with an abdominal strain and Corey Hulsey struggled in his place.

Oakland allowed nine sacks for its second straight Monday night game and it wasn’t as if Shawne Merriman and Shaun Phillips were doing it. Terrill, who came in with two sacks in 25 career games, topped that total in the first half, and Grant Wistrom got his first two of the season.

The Seahawks got into the end zone on their opening drive, moving the ball 68 yards with help from a personal foul against the Raiders’ coaching staff. Wallace used an exaggerated pump fake to get Fabian Washington out of position on the 22-yard scoring strike to Branch.

A 29-yard punt by three-time All-Pro Shane Lechler set up Josh Brown’s 20-yard field goal on Seattle’s next drive and Brown added a 25-yard field goal in the second quarter to make it 13-0. His final field goal was from 20 yards with 1:17 left in the game.

Notes: The shutout was the Seahawks’ first since Dec. 5, 2005, when they beat Philadelphia 42-0 in their most recent appearance on Monday Night. … Wallace’s 37-yard scramble in the third quarter was Seattle’s longest run of the season. … The Raiders have lost five straight overall on Mondays, being outscored 116-27 in the process.
