Alexei Yashin had two goals and an assist to extend his points streak to seven games in the New York Islanders' 4-3 victory over the Atlanta Thrashers on Tuesday night.
Miroslav Satan and Jason Blake also scored to help New York win for the third time in its last four games. Satan has seven goals this season, five in his last four games.
Rick DiPietro made 34 saves for his fourth victory.
Ilya Kovalchuk had two power-play goals and Bobby Holik also scored with the man advantage for Atlanta, which has lost five of its last six. The Thrashers' Patrik Stefan missed the net on a penalty shot in the second period.
Panthers 4, Penguins 3, OT
At Pittsburgh, Stephen Weiss' slap shot from the right faceoff dot eluded Pittsburgh goalie Jocelyn Thibault on a power play 53 seconds into overtime and Florida ran the Penguins' season-long winless streak to nine games.
The Penguins led 3-2 following goals by Dick Tarnstrom and Lasse Pirjeta in the third period, but the Panthers tied it on Lukas Krajicek's power-play goal with 2 minutes remaining in regulation.
Penguins owner-captain Mario Lemieux then drew a disputed interference penalty in the final 17 seconds of the period that carried into the overtime, and Weiss took advantage of it to score his first of the season.
Pittsburgh is 0-4-5, the longest season-opening stretch in its 39-season history without winning, and has dropped its last 10 against Florida.
