The 58-0 victory was the biggest shutout in Seattle's history. Leon Washington's 3-yard touchdown run with 2:32 left set a franchise record for points.
Arizona (4-9) was shut out for the first time since 2003 against Seattle. The effortless performance will only raise questions about Ken Whisenhunt's future as head coach. Arizona lost its ninth in a row overall.
