SEATTLE — Doug Baldwin picked a national stage to remind the rest of the NFL what they passed up in last April’s draft.

Baldwin, an undrafted rookie out of Stanford, blocked a first-quarter punt that was returned by Michael Robinson 17 yards for a touchdown, then caught a 29-yard TD pass from Tarvaris Jackson in the third quarter as the Seattle Seahawks pulled away for a 30-13 win over the staggering St. Louis Rams on Monday night.

Seattle (6-7) won for the fourth time in five games and kept alive its slim hopes for reaching the postseason. The Seahawks likely would need to win out to potentially make the playoffs a reality, but they’re at least back in the conversation after a 2-6 start.

“As far as my expectations go, I expected to be successful. I didn’t know how successful, but I expected to be able to come in here and win a job in some capacity, because if you don’t have that confidence in yourself you’re not going to win a job,” Baldwin said. “To be where I am now, no I didn’t expect this. But at the same time I’m not satisfied.”

Marshawn Lynch topped 100 yards rushing for the fifth time in the last six games, finishing with 115 on 23 carries. He scored a touchdown in his ninth straight game on a 16-yard run with 2:57 left to put away Seattle’s 13th win in its last 14 games against the Rams.
