The Seattle Seahawks cruised to victory on Sunday, defeating the Arizona Cardinals 17-3. Backup quarterback Drew Lock improved to 2-0 as a starter, and 3-0 overall this season. Lock continues doing enough in relief of Sam Darnold for the Seahawks to win games.

Make no mistake. It was a dominant defensive performance from Mike Macdonald's unit that powered the Seahawks to victory. They provided the opportunity, and Lock and the offense did enough to claim a straightforward victory.

Lock completed 19-of-28 passing attempts for 175 yards, one touchdown, and zero interceptions. The former Missouri was not sacked and did not commit a single turnover. Lock protected the football, took what the Cardinals' outmatched defense gave him, spreading the ball around as required.

Lock improved to 2-0 versus the Cardinals this season. He entered the Week 1 game versus the New England Patriots and helped Seattle win that contest as well. With Darnold struggling with recurring injury and inconsistent play, Lock has been very useful as a backup QB.

Lock momentarily entered the blue medical tent. Macdonald confirmed that Lock suffered an oblique injury. His status for Week 10 versus the Las Vegas Raiders hangs in the air, as does Darnold's. Hopefully the Seahawks will have Lock available.
