Purdy, 49ers topple Seahawks 21-13, win NFC West

SEATTLE — Rookie Brock Purdy, a pair of touchdown passes to George Kittle, and the San Francisco 49ers won their first NFC West title since 2019, beating the Seattle Seahawks 21-13 Thursday night.

Despite fielding their third quarterback this season, the 49ers (10-4) continued to show they could be the NFC’s class alongside Philadelphia. San Francisco won its seventh consecutive win and used its stifling defense to frustrate Seattle into countless errors.

The Niners got a handful of big games from their rookie quarterback. Playing on the road for the first time in his career, Purdy scored on his first 11 passing attempts, including a 28-yard TD against Kittle in the first quarter when Purdy ran two fakes before hitting his tight end wide open.

Purdy and Kittle reconnected early in the second half when the Seattle defense blew cover, leaving Kittle open for a 54-yard TD and a 21-3 lead for San Francisco. Purdy finished 17 of 26 for 217 yards and joined Aaron Rodgers as the only QB since at least 1950 to have a passer rating of at least 115 in each of his first two starts.

Kittle had four catches for 93 yards and Christian McCaffrey rushed for 108 yards, including a 1-yard TD run in the last minute of the first half after a Seattle turnover.

Seattle (7-7) lost for the fourth time in five games and its playoff hopes took another hit. Geno Smith threw for 238 yards and Seattle’s first offensive TD this season against the 49ers but was under constant pressure.

Seattle drew within a point late in the fourth quarter after Robbie Gould missed a 43-yard field goal and the Seahawks went 67 yards in 1:25. Smith hit Noah Fant on a 10-yard TD with 3:35 left. But Purdy converted a third and one with a scramble before the 2-minute warning, and Jordan Mason sealed the win with a 55-yard rush with 1:02 remaining.

Smith was fired three times and hit nine times. When he had time to throw, the open windows were small for his pass catchers. Seattle had a play longer than 20 yards.

And Seattle failed to capitalize on a 49ers error late in the first half.

Seattle scored its first offensive points in two games against the 49ers midway through the second quarter on Jason Myers’ 38-yard field goal. Seattle’s only points in the first matchup of Week 2 came from a blocked field goal that was returned for a touchdown.

But the Seahawks followed with two critical errors. Quandre Diggs dropped a possible interception that would have given Seattle the ball on the San Francisco side. And Travis Homer fiddled with a big hit by Dre Greenlaw at the Seattle 41 with 1:08 in the second quarter. The fumble was returned by Charvarius Ward after 35 yards, and two plays later McCaffrey scored to give the 49ers a 14-3 lead.

The 49ers have conceded 17 points or fewer in every game on their winning streak.
