The Edmonton Oilers scored five unanswered goals in a span of just over 17 minutes to erase a three-goal deficit in St. Louis, returning home a five-game win streak under their belts.

Gilbert Brule started the rally with two goals and Sam Gagner, Shawn Horcoff and Dustin Penner poured in their own in a four-goal final period for a 5-3 victory Friday night over the Blues.

Brule sparked the team by scoring with just 11 seconds remaining in the second period, which made it 3-1 St. Louis.

The Brule-Gagner-Penner line combined for nine points, with Penner topping the list with four points.

Jeff Deslauriers made 27 saves for Edmonton (15-13-4), which begins a four-game homestand Tuesday against Los Angeles.

The Oilers won the last five of their six-game trip.

"I think after winning five on the road, it's tough to play any better," Penner said. "It's tough to play any better than that."

David Backes scored twice for St. Louis (13-12-5), with T.J. Oshie also finding the mark.

Weak goals

Ty Conklin was tremendous through two periods, but contributed to the result in the third with a couple of weak goals allowed.

The Oilers simply wanted it more than the Blues in the final stanza.

"I got that feeling, after that second goal and just the way we were playing starting the third period, they were sitting back," Penner said. "Whenever a team does that, if you sit back, it becomes pretty hairy."

Penner and Barret Jackman were locked in a titanic battle for the puck on the sequence that led to the tying goal. Penner prevailed, working the puck over to Gagner, whose shot went off Conklin's pad and in at 11:19 of the third.

Horcoff put the Oilers up for the first time just over two minutes later, outfighting former teammate Brad Winchester for the puck and then heading to the net to redirect Robert Nilsson's pass.

The Blues did some good digging on the boards to set up the first goal, a Backes wraparound goal at 11:14

Edmonton was given an opportunity late in the first when Horcoff was cut by the stick of Patrik Berglund.

The four-minute penalty spanned the first and second periods, but the Oilers couldn't get much going.

Oshie had a strong short-handed chance for the Blues, but couldn't beat Deslauriers. The Oilers goalie was a bit shaken up in making the save, but shrugged it off.

The Oilers then allowed a short-handed breakaway on their next power play just two minutes later, but Deslauriers shut the door on Backes.

St. Louis connected on their own man advantage. Oshie caught Deslauriers too far off the post for a short-side goal.

Conklin was outstanding at the other end, taking a slapper off his shoulder and then regaining position to send Patrick O'Sullivan's follow up out of harm's way.

Backes put the Blues up by three goals at 15:35, and it had all the makings for a long third period for the Oilers. Defenceman Erik Johnson picked up his second assist of the game and 17th of the season.

Between pads

Brule, who now has nine goals, gave Edmonton life by scoring on a shot that seemed more harmless than many Conklin had faced. From the doorstep Brule snuck the puck between the goalie's pads.

Brule then completed a play started by Gagner and Penner, driving to the slot for a goal at 8:31.

"It's tough to get down three goals," Brule said. "But I think when I got that one late in the second it gave us a big boost. I think we were coming out of it the last seven minutes of the second and all of the third. I don't think they can handle our approach."

After Horcoff put Edmonton up, Andrew Cogliano nearly made it a two-goal lead just over one minute later but Conklin handled his backhander.

Deslauriers made his most important save, moving well laterally to deny veteran defender Darryl Sydor.

Not long after, Penner gave the Oilers a stranglehold with a sharp-angle goal.

"It's unacceptable," Blues defenceman Barret Jackman said. "Right after they got that goal at the end of the second period, it seemed like we flipped a switch and we were on our heels and weren't doing the things that got us success in the first two periods. We weren't skating when we got the puck, we were standing still."

Brule narrowly missed a hat trick with an empty-net bid.
