The Cardinals lost the first of a three-game stretch against division opponents. Murray threw for 175 yards and two touchdowns.
Collins gave the Cardinals some hope in the third quarter on his momentum-swinging pick-6. Smith lofted a short pass to the right side that was intended for Walker, but Collins shed a block and jumped into the throw's path, snatching the ball out of the air and running to the end zone.
But just like all season, the Cardinals were hurt by their own mistakes. They were called for 12 penalties and were plagued by dropped passes and botched snaps.
The Seahawks led 10-7 at halftime. They went ahead early in the second quarter when Smith found DK Metcalf for a 4-yard touchdown. The Seahawks caught a break on the previous play when cornerback Byron Murphy Jr. dropped a potential interception.
The Cardinals looked like they might score late in the first half, but Murray fumbled on a scramble when Seattle's Ryan Neal punched the ball out from behind. The Seahawks recovered.
It was Seattle's 16th forced fumble of the season, which leads the NFL.
