Pittsburgh, PA (Sports Network) - Ben Roethlisberger completed 18 of 22 passes for 206 yards and a touchdown as an undermanned Pittsburgh Steelers squad dominated time of possession and totally silenced the Seattle Seahawks offense in a 21-0 win at Heinz Field.

Willie Parker carried 28 times for 102 yards and Najeh Davenport chipped in with seven carries for 58 yards and two touchdowns. Roethlisberger was remarkably efficient, completing his final 13 pass attempts.

Pittsburgh (4-1), which was without receivers Hines Ward and Santonio Holmes as well as defensive starters Troy Polamalu and Casey Hampton, controlled the ball for over 40 minutes and limited the Seattle offense to 144 yards. Cedrick Wilson caught five passes for 69 yards and Heath Miller had four catches for 44 yards and a score.

"(Being 4-1) is a huge, huge deal," said Roethlisberger afterward. "4-1 feels really good going into a week where we can get everybody back and healthy. It's a good time for us to have a rest."

Matt Hasselbeck completed just 13 of 27 passes for 116 yards and threw an interception in the end zone that cost Seattle its only true scoring chance, while running back Shaun Alexander carried 11 times for just 25 yards.

The Seahawks (3-2) managed just seven first downs on the day, and didn't move the chains in the second half until their final drive.

"Offensively we were not very good today," said Seahawks head coach Mike Holmgren. "Give the Steelers credit for that. Our defense had to be on the field too long, and when we had a chance to get off the field we couldn't. The time of possession was ridiculous and typically when that happens you don't do well."

Both defenses were stiff through the first, while both Hasselbeck and Roethlisberger struggled to find their groove, and the game was scoreless well into the second quarter.

Late in the second, Pittsburgh finally broke through when Davenport rattled off a 45-yard run to set them up at the Seattle 20. Three plays later, the Steelers lined up three receivers wide to the left, then sent Miller down the right seam, where Roethlisberger hit him for a 13-yard touchdown in front of a stumbling Marcus Trufant.

Seattle threatened on its final drive of the first half, as Hasselbeck completed a 30-yard pass to Ben Obamanu and then hit Marcus Pollard for 22 yards. But on a second down from the Pittsburgh 14, Hasselbeck was intercepted by Ike Taylor in the corner of the end zone, on an out route intended for Obamanu, to end the half.

The Steelers then opened the second half with a drive that elapsed over ten minutes, using 17 plays to go 80 yards before finally taking a 14-0 lead with 4:47 remaining in the third. Roethlisberger hit Wilson for gains of 15 and 11 yards, but Pittsburgh mostly used the smashmouth combination of Davenport and Parker to move the ball.

Parker scampered around the left end for a 20-yard run that was originally called a touchdown. He was ruled out of bounds at the one-yard line after a review, and two tries later, Davenport pounded it home for the score.

Seattle went three-and-out on its next possession, and Pittsburgh went back to its ball-control perfection. A drive that began with more than three minutes to go in the third culminated in Davenport banging his way into the end zone from five yards out with 10:11 left in the fourth. Parker carried six times on the 85-yard drive, while Roethlisberger completed his only two pass attempts - an 18-yarder to Wilson and a 17-yard catch-and-run by Davenport.
