PHILADELPHIA — The Rangers waited to start getting serious about Wednesday night’s game against the Flyers for about as long as they’ve been waiting for Patrick Kane himself.

They got away with it, though, as Vladimir Tarasenko scored 2:32 into overtime to give the Blueshirts a 3-2 victory.

More ragged than rugged for most of the night, the Rangers perked up midway through the third period when Chris Kreider deflected Tarasenko’s shot to even the score at 2.

It was Kreider’s 26th goal of the season, getting him halfway to last year’s once-in-a-lifetime output.

The Rangers played the game with a lineup that was two men short, dressing 11 forwards and five defensemen.

Kane was missing up front. Ryan Lindgren, listed as day-to-day with an upper-body injury, and K’Andre Miller, serving the first game of his three-game suspension, were out, and Braden Schneider was back on the ice.

On Thursday, they will be back to 18 skaters. Kane will play and the Rangers will be eligible to call up a defenseman (likely Libor Hajek or Matthew Robertson) if Lindgren can’t return.

The game’s opening goal on the power play was a work of Artemi as Panarin started a crisp tic-tac-toe sequence that went from his stick to Tarasenko’s to Mika Zibanejad’s to the back of the net in rapid fashion.

A sizable contingent of New York fans in the arena got up an audible version of the Rangers’ goal song before being shouted down.

Boos for Tony DeAngelo and chants of “I-gor” filled the air throughout. Denis Potvin’s name was even brought up at least once.

The Rangers were unable to match their faithful’s intensity, until they did.

Three minor penalties stalled their momentum.

On the third one, Adam Fox lost control as he was trying to fish the puck out of the corner and it squirted in front to Owen Tippett, who flicked it past Igor Shesterkin.

Then in the second period, Scott Laughton swooped in along the goal line and sent a shot just inside the crossbar to give the Flyers the lead that wouldn’t last.
