Denis Potvin last night became the first NHL defenseman to score 300 goals and Pat LaFontaine and Brent Sutter had two goals apiece, leading the New York Islanders to an 8-5 win over the visiting Quebec Nordiques.

Potvin, a 15-year veteran, beat goalie Ron Tugnutt at 4:24 of the second period on a power play. Potvin picked up a loose puck in the long slot and fired through traffic from 35 feet, giving the Islanders a 5-3 lead.

Potvin leads all NHL defensemen with 1,030 points. He is the only NHL defenseman to have reached 1,000 career points.

Flyers 3, Sabres 1: Dave Brown scored two goals and the Flyers ended Buffalo's six-game winning streak with a victory in Philadelphia.

The win allowed Philadelphia to regain first place in the Patrick Division, one point ahead of the Washington Capitals and the Islanders.

Brown's first goal put the Flyers in front, 2-1, with 1:55 remaining in the first period. He skated the length of the ice and pushed the puck past fallen goalie Jacques Cloutier.

After a scoreless second period, Brown followed his own shot and beat Cloutier over his glove to make it 3-1 just 56 seconds into the third period.

Bruins 3, Canadiens 2: In Boston, Reed Larson and Steve Kasper scored goals 58 seconds apart late in the third period, lifting the Bruins to victory over Montreal in a game during which referee Dave Newell handed out 142 minutes in penalties.

Newell called 12 major penalties for fighting, a pair of 10-minute misconducts and 32 minors. In the scoreless first period, which took just less than one hour to play, there were 27 penalties for a total of 66 minutes.

Larson scored at 17:48 of the third period, atoning for a mistake that had enabled Montreal to tie the game 14 seconds earlier. Kasper, set up by Cam Neely, then made it 3-1 at 18:46.

The victory returned the Bruins to first place in the Adams Division, a spot they had relinquished with a 5-4 loss in Montreal Wednesday night.

Blues 3, Whalers 2: In St. Louis, Rick Meagher fired a 30-foot shot over Mike Liut's right shoulder with 1:05 left to play in the third period, allowing the Blues to end a five-game losing streak.

The Blues, playing without six injured forwards, had lost seven of their previous eight games during the team's worst slump in four seasons.
