His only other previous Stanley Cup Playoff goal in overtime is a series-winner for the Carolina Hurricanes against the Toronto Maple Leafs in Game 6 of the 2002 Eastern Conference Final.
The Flames advance to the Western Conference Final in their first trip to the playoffs in eight years.

The victory gives the Bruins a 2-0 lead in the best-of-7 series.
1995: Penguins forward Jaromir Jagr has an assist in a 4-3 season-ending loss to the Florida Panthers to become the first European-born and -trained player to lead the NHL in scoring. Jagr and Eric Lindros of the Philadelphia Flyers finish the 48-game season with 70 points, but Jagr is awarded the Art Ross Trophy because he scores 32 goals, three more than Lindros. It's the first of five scoring titles for Jagr in a span of seven seasons.

Kings forward Marian Gaborik ties the game with 7.0 seconds remaining in the third period, then gets the winner at 12:17 of overtime. His heroics spoil the night for the Ducks and forward Teemu Selanne, whose third-period goal would have been the game-winner.
