Pittsburgh, PA – Ben Roethlisberger and the Pittsburgh 0.
Roethlisberger completed 22-of-30 passes for 298 yards and a touchdown and played mistake-free after accounting for five of the Steelers' seven turnovers in a 35-7 drubbing against the Ravens last Sunday.
"It's not going to take one performance to get that stench off us," Steelers head coach Mike Tomlin said.
Tarvaris Jackson passed for just 159 yards on 20-of-29 attempts, as Seattle (0-2) recorded just eight first downs to Pittsburgh's 23.
The last time the Seahawks were shut out also came at Heinz Field, as they fell to the Steelers, 21-0, on October 7, 2007.
Mendenhall was stuffed on 4th-and-goal from the one on the game's opening possession, but atoned for the missed opportunity by barreling into the end zone from the same spot with 3:28 remaining in the first quarter.
Isaac Redman made it 14-0 early in the second when he took a handoff up the middle and went in for a 20-yard TD, and Shaun Suisham added a 20-yard field goal less than two minutes before the half.
The Steelers essentially put the game away with a nine-play, 71-yard drive in the third. Hines Ward tip-toed the left sideline to haul in a key 15-yard pass on third down, and two plays later Roethlisberger connected with Wallace in the left corner of the end zone on a fade route.
This was Pittsburgh's first shutout since blanking Cleveland, 31-0, on December 28, 2008...Seattle was out-gained, 421-164, amassing just 31 rushing yards...Wallace posted his fifth straight 100-yard receiving game...James Harrison recorded one of Pittsburgh's five sacks, becoming the fifth Steeler with 50-plus in his career...The last time the Seahawks started the season 0-2 was 2008, when they finished 4-12.
