ST. LOUIS — Wide receiver Percy Harvin is gone, now property of the New York Jets after a bombshell trade Friday, but the Seattle Seahawks still have other issues to fix in order to resemble the Super Bowl champions they were last year.

As for the St. Louis Rams, they were just glad to finally hold on to a large lead in the Edward Jones Dome after blowing 21- and 11-point advantages in losses to Dallas and San Francisco.

Quarterback Austin Davis threw for 152 yards and a pair of touchdowns as St. Louis snapped its three-game losing streak Sunday with a 28-26 upset of its NFC West rivals from Seattle.

Outgained 463-272, the Rams (2-4) enjoyed a huge advantage in special teams. A 75-yard kickoff return by running back Benny Cunningham set up their first touchdown, a wacky, trick-play, 90-yard punt return by wide receiver Stedman Bailey gave them a 21-3 lead in the second quarter and a fake punt in the fourth quarter helped them protect a slim advantage.

Seattle quarterback Russell Wilson became the first player in NFL history to pass for more than 300 yards and rush for more than 100 yards in the same game. He completed 23 of 36 passes for 313 yards and two touchdowns while rushing seven times for 106 yards and a 19-yard third-quarter score.

But it was not enough to prevent the Seahawks’ second straight loss to drop their record to 3-3.

On fourth-and-3 from its 18, St. Louis had punter Johnny Hekker throw to Cunningham. It resulted in an 18-yard gain and a critical first down with less than three minutes left.

“I had a touchdown against them,” said Hekker, who threw for a touchdown on a fake field goal two years ago to help beat Seattle. “I’m not going to say that was the best play of my career, but as far as being clutch, that’s pretty sweet.”

“Gutty call by (Rams coach) Jeff (Fisher),” Seattle coach Pete Carroll said. “We’ve seen him do that before, but I didn’t think he’d do that from that spot on the field. If he drops the ball, we have it at their 18. We can kick a field goal and get out of here with a win.”

Instead, St. Louis kept the ball and sealed the win when rookie running back Tre Mason picked up 9 yards on a third-and-1 run inside the final minute. Mason was stripped from behind by cornerback Richard Sherman, but referee Brad Allen’s crew ruled that tight end Cory Harkey outfought free safety Earl Thomas for the ball at the Seahawks’ 32.

Perhaps frustrated by the loss and his team’s 10 penalties for 89 yards, as compared to the Rams’ two flags for 20 yards, Thomas blasted the officials.

“We’re not only having to play the other team, we have to play the officials every week,” he said. “That’s not right. Every week, it seems like the calls go against us.”

Thomas also correctly noted St. Louis’ dominance in the kicking game, symbolized by Bailey’s stunningly easy touchdown after Seattle totally fell for a fake by punt returner Tavon Austin.

Running to the left sideline after John Ryan punted, Austin faked a sliding catch. The pantomime took nearly every Seahawk away from the right side, where Bailey made an over-the-shoulder grab. Bailey needed to elude just two defenders and had clear sailing for about the last 55 yards.

Carroll argued unsuccessfully that Austin signaled for a fair catch.

“That was a great fake,” Carroll said. “We were tracking their blockers instead of the ball.”

What the Rams said:

“As long as we ended with a win, I was happy.” — RB Tre Mason.

What the Seahawks said:

“I was actually encouraged. We did everything we had to do to get back into the game in the second half.” — Coach Pete Carroll.

What we learned about the Rams:

1. It might have taken seven weeks into the season before the coaches figured it out, but they might have found third round gold in running back Tre Mason. The rookie from Auburn ran with a burst, picking up a team-high 85 yards on 18 carries and his first NFL TD. Mason also sealed the game with a 9-yard run in the last minute, although he was fortunate that his fumble was recovered by tight end Cory Harkey. Mason should get the bulk of the carries going forward.

2. Coach Jeff Fisher’s reputation for special teams genius won this game. Not only did the Rams pull off a wacky fake punt return touchdown in the second quarter that embarrassed Seattle, they also came up with a gutsy fake punt from its 18 that resulted in a critical first down which helped melt the last three minutes off the clock. Plays like that, and Benny Cunningham’s 75-yard kickoff return which set up the first TD, are why the Rams won despite being outgained by nearly 200 yards.

–WR Kenny Britt (ankle) missed time in the first quarter, but returned to the game and finished with two catches for four yards. Britt, who has 14 receptions for 197 yards, should be able to play next week at Kansas City.

–CB Janoris Jenkins (knee) limped off the field in the second quarter, but didn’t miss much time. The third-year pro notched a team-high nine tackles and broke up a pass. He figures to be able to play next week.

–DE Robert Quinn finally notched his first sack of the season in the second quarter, capping a six-play stretch in which St. Louis nailed QB Russell Wilson three times. Quinn had a team-high 19 sacks last year, but like the team, hadn’t been able to find the quarterback much until Sunday. The Rams came into the game with only one sack.

What we learned about the Seahawks:

1. Special teams play was simply awful. Seattle gave up a long kickoff return to set up a cheapo TD, but that was highlight-reel material compared to the 90-yard TD punt return by St. Louis’ Stedman Bailey in the second quarter. Eight Seahawks were caught watching the fake catch near one sideline by Tavon Austin, only to see Bailey zipping down the right sideline. Whatever happened to the concept of tracking the ball?

2. QB Russell Wilson did everything in his power to win the game. Wilson accounted for 419 total yards, 313 in the air, and led three second half TD drives with one big play after another. He got little support from an offensive line which gave up three sacks in a six-play span during the second quarter and committed a spate of penalties. Seattle might not have won, but it can’t blame Wilson.

–FB Derrick Coleman broke his foot during pregame warm-ups, leaving the team without a fullback. It’s not known how much time he will miss. Seattle used backup RB Robert Turbin more in Coleman’s place, but Coleman’s absence might have led to RB Marshawn Lynch gaining only 53 yards on 18 attempts.

–CB Tharold Simon missed time in the first half with an ankle injury, but was able to return to the game. Simon managed just one tackle and committed a pair of penalties on a Rams’ scoring drive that led to first downs, the second one wiping out a third-and-goal at the 25 in the second quarter.

–QB Russell Wilson became the first player in NFL history to pass for 300 yards and rush for 100 in the same game, a feat which couldn’t help the Seahawks win. Wilson compiled 264 of his 419 total yards in the second half as he almost rallied Seattle from a 21-6 halftime deficit.
