SEATTLE (AP) -- Marshawn Lynch had three touchdown runs and Seattle set a franchise record for points in a 58-0 win over the Cardinals on Sunday.
The Seahawks forced eight turnovers. Richard Sherman and Bobby Wagner each had two interceptions.
Seattle (8-5) kept firm grasp on the final NFC wild-card spot and kept alive slim chances of catching San Francisco in the NFC West race. The Seahawks also picked up their first division victory and assured coach Pete Carroll of his first eight-win season in three years with them.
The 58-0 victory was the biggest shutout in Seattle's history. Leon Washington's 3-yard TD 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 straight overall.
