VERY BAD NEWS: New York Rangers Head Coach Angry and Announced resignation immediately today….

Adam Fox scored 36 seconds into overtime and the New York Rangers became the first NHL team to clinch a playoff spot this season, beating the Philadelphia Flyers 6-5 following a wild third period Tuesday night.

Alexis Lafreniere had two goals and Igor Shesterkin made 36 saves for the Rangers, who lead the league with 100 points after giving coach Peter Laviolette his 800th career win.

New York technically secured its third consecutive playoff berth just by getting to overtime and earning one point after Detroit lost to Washington in OT.

But after the teams traded seven goals in a frenetic third period, it didn’t take long for Fox to finish the night in style with a pinpoint wrist shot from the high slot for his 15th goal, adding to the star defenseman’s career high.

“For us to stay as consistent as we have says a lot about our group,’’ said Fox, who has points in eight straight games. “It’s big for us to clinch that playoff spot. It’s just the first step.”

Vincent Trocheck, Mika Zibanejad and Jonny Brodzinski also scored for the Rangers, who extended their Metropolitan Division lead to three points over Carolina, which lost 4-1 at Pittsburgh. Trocheck also had two assists.

“I thought we battled hard. We knew this would be a tough game,” Zibanejad said. “I thought we got better as the game went on. We kept fighting.”
