It's the stuff rivalries are made of.

Game 1 of the first-ever postseason meeting between the Sharks and Kings had it all: huge momentum swings, a rare playoff fight, a hit that caused an injury and had the home side fuming, an overtime period, and in the end, a familiar hero.

Sharks center Joe Pavelski roofed a goal off a centering pass from Kyle Wellwood 14:44 into overtime to lift the Sharks to a 3-2 win in the first game of the first-round series in front of a sellout crowd at HP Pavilion on Thursday night.

That's the same Joe Pavelski who became a household name even for non-hockey fans in the Bay Area last season when he scored a team-high 17 points in the playoffs. It was his third career overtime playoff goal.

Wellwood said when he got the puck and saw Pavelski, he knew where his pass was going. "He's been scoring a ton lately ... and he's got some history," Wellwood said.

The final goal came more than three hours after the Sharks opened the scoring with their fastest-ever playoff goal, Dany Heatley burying the rebound of a Ryane Clowe bad-angle shot 28 seconds into the first period. The Sharks didn't let up in the first, outshooting the Kings 14-3, but couldn't extend their lead.

"It started the way we wanted," said Clowe, who had three assists. "But we knew they were going to come back, and they did."

The turn came after a controversial hit that injured Sharks defenseman Ian White late in the first period. A fight between San Jose's Ben Eager and Los Angeles' Kyle Clifford followed, and by the time Clifford had won in a unanimous decision, the Kings had stolen the momentum.
