Corey Perry scored the winner 2:26 into overtime as the Anaheim Ducks eliminated the Calgary Flames with a 3-2 win in Game 5 on Sunday night in California.

Matt Beleskey and Ryan Kesler also scored for the Ducks, who advanced to the Western Conference final for the fourth time in franchise history and first since winning the Stanley Cup in 2007.

"My first career [goal] in overtime in the playoffs. It feels pretty good," said Perry.

The Ducks got a scare when Perry, who now leads the NHL with 15 points this post-season, was on the wrong end of a brutal-looking knee-on-knee hit from Matt Stajan late in the second period. Perry had to crawl to the bench, unable to put any weight on his right leg, but returned to the bench a few minutes later and received a huge ovation.

"Didn't feel great when it happened, I didn't know what was going on," said Perry of the injury. "I mean it calmed down after a few minutes, I started walking around but I mean you do anything to come back and help the team win at any point in the season, especially in the playoffs."

Perry earned bigger cheers when he put a Patrick Maroon rebound past Ramo as he was sprawled on the ice to end the game. The Ducks blistered Ramo throughout, and turned up the heat to start overtime, with seven shots in less than three minutes.

Frederik Andersen made 17 saves, while his Flames counterpart Karri Ramo turned away 44-of-47 shots.

"I'm rooting for them [Ducks]," said Calgary coach Bob Hartley. "We didn't give them anything. They earned it. They were the better team and you just have to tip your cap to them because they worked hard and they battled and they finished on top of the conference all season so it's not by luck that they beat us."

The Ducks will have home-ice advantage in the next round against the Chicago Blackhawks, which bodes well for the Pacific Division champions. They are 5-0 at Honda Center, thanks in large part to their prowess on both the power play and penalty kill.

After conceding a power-play goal at home for the first time this post-season to open the scoring on Jiri Hudler's slapshot 10:43 into the first period, the Ducks responded by reclaiming the special teams edge.

Jakob Silfverberg found Kesler for a one-timer blast to capitalize on Joe Colborne's attempt to put Hampus Lindholm in a sleeper hold, tying the game at 1-1.

The Ducks have now converted on 7-of-19 power plays this post-season, a staggering 36.8 percentage.

The Flames responded 56 seconds later to retake the lead. Gaudreau eventually capitalized on the Ducks' failure to clear the puck in their own zone, scoring his second goal of the series and fourth of the post-season.

Hudler had an assist on the play, as the Flames finally got some much-needed scoring punch from their top line. The combination of Hudler, Gaudreau, and Monahan had accounted for only two goals and one assist through the first four games of the series.

Dennis Wideman added two assists for his second multi-point game of the post-season. He was also effective in helping stifle the Ducks' dominant offence by blocking nine shots, but it wasn't enough to stave off elimination.

Beleskey set a new Ducks' post-season record with his fifth straight game with a goal when he redirected Francois Beauchemin's power-play shot 59 seconds into the third period to tie the game at 2-2.

"I think they're a team that in the future is going to be very very good," said Anaheim coach Bruce Boudreau. "When those guys, they get a little bit more experience and what they do in the off-season, that's a team that I wouldn't...I think is going to be very good next year."
