Mike Richards and Chris Pronger added power-play goals for Philadelphia, which extended its season-best winning streak to five games.

In the second period, Brandon Dubinsky fired a rebound from Michael Del Zotto’s shot past goalie Sergei Bobrovsky. Dubinsky leads the Rangers with eight goals in 12 games.

Philadelphia scored the next three goals against Henrik Lundqvist, who started despite being hit on the right side of his neck in practice Wednesday.

Richards tied the game at 5:12 with a one-timer from one knee. More than four minutes later, Betts gave the Flyers the lead when he fetched his own rebound and backhanded a shot past Lundqvist.

Zherdev added the last goal when the pass he sent toward the net took a funny hop and bounced over Lundqvist’s shoulder.

Senators 4, Islanders 1 — Jason Spezza had a goal and three assists as Ottawa handed visiting New York its sixth straight loss.

Spezza, held without a point in his first two games back from a groin injury, set up goals by defensemen Sergei Gonchar and David Hale before scoring his second of the season to put Ottawa up by three 6:17 into the second period.

Spezza got his third assist when Chris Kelly scored into an empty net with 12.5 seconds remaining. Peter Regin had two assists.

Matt Moulson spoiled Elliott’s shutout bid with a power-play goal 3:40 into the third.

Blues 2, Sharks 0 — David Perron made San Jose pay once he recovered from Joe Thornton’s elbow to the head, helping St. Louis win its sixth in a row at home to start the season.

Jaroslav Halak earned his third shutout, and Thornton drew a five-minute major penalty and game misconduct for head contact after his check early in the second period sent Perron sprawling to the ice.

Blue Jackets 3, Thrashers 0 — Mathieu Garon stopped 25 shots for his second straight shutout and Columbus beat host Atlanta.

Derick Brassard scored for the fifth time in six games, 4:46 into the second period.

Brassard also had an assist when Marc Methot scored midway through the third period for a 2-0 lead. R.J. Umberger added an empty-netter.

Canucks 3, Avalanche 1 — At Denver, backup goalie Cory Schneider stopped 33 shots, Ryan Kesler scored the first of three power-play goals, and Vancouver won its fifth straight.

Henrik Sedin and Raffi Torres also scored on the power play for the Canucks, while Daniel Sedin added two assists.

David Van Der Gulik, formerly of Boston University, scored his first NHL goal late in the game, spoiling ex-Boston College star Schneider’s bid for his first career shutout.

Kings 1, Lightning 0 — Jonathan Quick made 24 saves to improve to 8-1 and Justin Williams scored in his fourth consecutive game as host Los Angeles beat Tampa Bay.
