SEATTLE (AP) -- Marshawn Lynch scored on a 9-yard run with 12:07 remaining, Bruce Irvin returned an interception 49 yards for a touchdown and the Seahawks wrapped up home-field advantage through the NFC playoffs with a 20-6 win over the St. Louis Rams on Sunday.
The two fourth-quarter touchdowns by Seattle (12-4) capped a six-game win streak to end the regular season. That earned the Seahawks a second straight NFC West title and the ninth division title in franchise history.
The NFC playoffs will go through Seattle for the second straight season.
St. Louis (6-10) couldn't take advantage of two first-half turnovers by the Seahawks and its only points came on a pair of field goals from Greg Zuerlein.
