OTTAWA • The night before the Blues faced the Senators, David Perron visited a local hockey goods store in Ottawa. After spotting a shooting alley inside, he grabbed a stick and, remaining unidentifiable to the sales clerk, ripped shots for a half-hour.

"He said, 'You've got a helluva shot,'" Perron said. "I just started laughing and said, 'Thanks.' He probably thought I was some junior (hockey player) that played a while back and stopped playing. It was pretty funny. I never told him who I was."

One of several of the Blues' struggling offensive players, Perron made his presence known Tuesday, scoring twice in the team's 3-1 victory over the Senators at Scotiabank Place.

"I guess I'll have to find a store in New Jersey, too," joked Perron, as the Blues packed their bags for the final game of the three-game trip Thursday against the Devils.

The Blues also picked up a goal from Chris Porter, breaking the two-goal plateau for only the second time in their past 10 games and helping the club leave town with an important road win — its first win in Ottawa in 12 years.

Starting Saturday in Nashville, Blues players began wearing T-shirts around the locker room that read: "2012 Road Warriors." They entered the game Tuesday with a mark of 8-11-3 on the road, losing four of their past five on foreign ice.

In order to change that, the Blues need more production from players such as Perron, David Backes and T.J. Oshie, who each entered the game Tuesday pointless in their past four games.

"You're going to have to get that if you're going to win on the road," Blues coach Ken Hitchcock said. "Your best players have to score. We've struggled in that area here lately, but tonight was big."

All three players contributed on Perron's second goal of the game, giving the Blues a 3-1 lead at 6 minutes, 35 seconds of the second period. Oshie stripped Ottawa's Erik Karlsson of the puck, which trickled to Backes. He fed Perron, who skated past the crease and flipped a shot past goalie Alex Auld.

"It was good to get in the (celebratory) huddle again," Oshie said.

The Blues' protected the two-goal cushion with a strong penalty-kill in the third period, following a hooking penalty against Patrik Berglund with 8½ minutes left in regulation. The team finished with 20 blocked shots, including four apiece by Barret Jackman and Roman Polak.

Blues goalie Brian Elliott made his first appearance against Ottawa since the team traded him last season. And while there was no standing ovation from Senators' fans afterwards, ala Jaroslav Halak in Montreal, Elliott was solid despite playing for the first time since Jan. 24. He picked up his 16th victory of the season with 28 saves, including a third-period stop on the Sens' Kyle Turris with the game hanging in the balance.

"I haven't played in a little bit, so just getting back out there and trying to do my best for the guys and give us a chance to win — that's what it meant," Elliott said. "You really want to get back in that winning feeling and ... doing it here is pretty big for me."

The Blues chased Ottawa starter Craig Anderson from the game after he allowed two goals on four shots.

Only 1:37 into the game, Porter deflected a shot by Polak, giving Porter his fourth goal of the season and two in a row for the Blues after Saturday's tally in Nashville.

"Porter chips in again," Hitchcock said. "Porter is really helping us right now. He's really playing well."

Perron put the Blues ahead 2-0 with the first of his two goals. Berglund put a shot on net and Anderson allowed a big rebound, giving Perron room to crash the crease and score his fifth goal of the season.

Ottawa inserted Auld and early in the second period trimmed their deficit to 2-1 on a power-play goal by Daniel Alfredsson. That ended the Senators' overall scoring drought at 103:04.

But Perron followed with No. 6 with 13:25 left to play in the second period, saying afterwards: "It's good to get a couple of goals offensively. Even better when you get two points like we did tonight. I thought maybe we would need more shots, but I felt like our shots were quality shots and that's what we need."

The Senators outshot the Blues 29-18, but the Blues scored their most goals since a 4-2 win over Buffalo on Jan. 21.

"Hopefully, we're back on track with a little more depth in scoring," Backes said. "We're not going to complain how it happens. The fact is, we got two points out of the night, and we'll move on to another tough place to play in New Jersey."
