PHILADELPHIA — It was a couple years ago that the Flyers were down in Florida on a roadtrip while Shayne Gostisbehere was holding down the fort in Philadelphia.

The Flyers’ third-round pick in 2012 had a goal and two assists and was a plus-7 in a 7-4 championship win over Minnesota for Union College and was named the most outstanding player in the Frozen Four.

Now he’s back at the NHL level, after a knee injury claimed most of last season, and is stepping right in to quarterback the Flyers’ power play with Mark Streit out six weeks. The veteran defenseman had surgery Tuesday to repair a detached pubic plate.

Gostisbehere, 22, is suddenly in the spotlight. At 3:41 of the first period, with the Flyers on the power play, he fired his first NHL goal past one of the game’s best goalies, Jonathan Quick.

“If they tell me to shoot, I’m going to do whatever they say,” Gostisbehere said after the morning skate. “Last game (Claude Giroux) said, ‘I want 10 shots from that place.’ I’m going to shoot the puck every chance I get because I don’t want to get yelled at by G and again, I’ll do whatever he says.”

Giroux fed him the puck and he ripped a slapshot past Quick to give the Flyers a 1-0 lead over the Los Angeles Kings.
