Ilkka Sinisalo scored 12:59 through the final period yesterday in Chicago to give the Philadelphia Flyers a 2-2 tie with the Black Hawks.

The Black Hawks stretched their first-place lead over idle St. Louis in the Norris Division to seven points. The Flyers, playing their second tie in two days, increased their Patrick Division lead to six points over idle Washington.

After a stretch of 36 scoreless minutes since Chicago mounted a 2-1 lead, Sinisalo scoring his season's 25th goal from just outside the crease on a power play scramble in front of goalie Bob Sauve.

Earlier, Chicago's defense had killed off six Philadelphia power plays. All told, the Flyers outshot the Black Hawks, 46-26, but only had one try on goal in the five-minute overtime while thwarting two.

"We are now about two for our last 30 tries," said Flyers Coach Mike Keenan, still disturbed about his team's recent lack of production in man-advantage opportunities. "I am not happy about getting just the one point, because we clearly dominated the game." The Flyers miss Tim Kerr, who has 25 power play goals but has been out with flu.

Denis Savard had Chicago ahead, 2-1, at 16:18 of the opening period, driving a slap shot past goalie Bob Froese for his 37th goal. Sabres 4, Oilers 2

Doug Smith scored two goals in the final 1 minute 50 seconds to give Buffalo its fifth straight victory, at home over Edmonton. He ended a 2-2 tie by sliding the puck under goalie Grant Fuhr after a net-front scramble, and added an empty-net goal with six seconds left.

Jari Kurri put the Oilers up, 2-1, with his 41st goal, off a Wayne Gretzky assist on a power play. Mike Foligno tied it after two Edmonton defenders missed the puck at the blueline, creating a two-on-none for Smith and Foligno. Nordiques 4, Bruins 3

In Boston, Peter Stastny scored with 11 seconds left in overtime as Quebec spoiled a comeback by the home team and built its season record against the Bruins to 4-0-1.

Stastny, set up by Mark Kumpel and Alain Cote, circled the net and poked the puck past Pat Riggin at the corner for his 29th goal.

The Bruins absorbed their third loss in four days, but not before goals by Randy Burridge and Ray Bourque 56 seconds apart midway through the third period erased a 3-1 lead provided by Michel Goulet's 36th goal for Quebec. It was No. 300, career, for Goulet.

The Bruins, beaten by Buffalo and the New York Rangers despite outshooting the two teams by a whopping 81-40 total, this time got 33 shots to 23 for Quebec. Devils 6, Whalers 3

Aaron Broten, Greg Adams and John MacLean scored two goals apiece in Hartford and enabled New Jersey to break an 11-game winless streak.

Paul Gagne set up four goals in the third period, two each by MacLean and Adams, as the Devils ended a run of seven losses and extended the Whalers' slump to seven straight defeats. At 26-27-1, the Whalers are under .500 for the first time since Dec. 11. Flames 7, Kings 3

In Inglewood, Calif., a 1-1 game after two periods turned into a scoring binge and Joe Mullen made two of three Calgary goals in a 48-second span against Los Angeles.

The Flames took advantage of a five-minute major penalty for high-sticking called on Kings defenseman Grant Ledyard at 7:39 of the period. Calgary broke the club record of three goals in 52 seconds and tied the club high for goals in a period with six. Jets 3, Canucks 3

Winnipeg gained the tie at Vancouver by rallying from a 3-1 deficit after two periods on goals in a 63-second span, by newly acquired Bill Derlago at 2:22 and Jim Nill from the edge of the crease at 3:25 of the third. Nill's goal was set up by Laurie Boschman, who came out of the corner and beat defenseman Garth Butcher before sending the pass to Nill.
