EDMONTON - Melker Karlsson scored early in the first overtime as the San Jose Sharks came back to beat the Edmonton Oilers 3-2 on Wednesday night in Game 1 of their Western Conference quarter-final series.

The game saw the Oilers jump out to a 2-0 first-period lead only for the veteran Sharks to come back and tie the game with just over 15 minutes to play.

Milan Lucic and Oscar Klefbom scored for the Oilers before 18,347 fans at sold-out Rogers Place.

Joel Ward and Paul Martin replied for San Jose in regulation time.

Edmonton centre Connor McDavid, the NHL's leading scorer in the regular season, had one assist in his playoff debut to extend his points streak to 15 games.

It was the first playoff game in the Oilers' new downtown arena and the team's first NHL post-season game in almost 11 years.
