CALGARY, Alberta (AP) -- As long as the game goes into overtime, the Calgary Flames are set.

Cory Stillman's power-play goal with 37 seconds left in overtime gave the Calgary Flames a 4-3 win Wednesday night over the league-leading San Jose Sharks.

Calgary improved to 5-9-2 with all five wins coming in overtime. The Flames have yet to lose in a league-leading seven OT contests.

"Overtime is supposed to be for a lot of skilled players because it opens up the ice and with our team, we do have the skilled players," said Stillman, who's goal was his first in 11 games.

With Owen Nolan in the penalty box for tripping, Calgary converted the four-on-three advantage when Stillman jammed in a rebound of a Valeri Bure shot past a sprawled Mike Vernon.

"I got my glove on the third rebound and I thought I had it under me but I guess I didn't," said Vernon. "Kerry (referee Fraser) claims he had a better view of it than I did but I thought I had it under my pad."

Also scoring for the Flames were rookie defenseman Robyn Regehr, Jarome Iginla, and Valeri Bure, with his 11th.

It was the first NHL goal for the 19-year-old Regehr, who missed the first month of the season recovering from a serious auto accident in which he suffered two broken legs last July.

"San Jose is a great team but we came out, worked hard, and kept going at them," said Regehr. "It took 65 minutes but we won the game."

Marco Sturm, Stephane Matteau, and Alexander Korolyuk scored for San Jose (11-7-2)

The regulation tie kept San Jose atop the NHL's overall standings with 25 points, one ahead of the Ottawa Senators, who beat the New York Rangers 4-3.

Grant Fuhr made his ninth consecutive start for Calgary, which outshot San Jose 29-26.

Iginla tied the game for Calgary 3-3 with 5:55 left in regulation.

The goal came less than three minutes after Korolyuk gave the Sharks a 3-2 lead with a slap shot that beat Fuhr.

Calgary led 2-1 after the first period, marking the first time this season they have led in a game after 20 minutes.

The Flames took a 1-0 lead at 7:31 when Regehr scored on a long shot from the blue line. It was only the third time this season Calgary had scored first.
