Someday, maybe 40 years from now, Philipp Grubauer will tell his grandchildren about how he shut out the Broad Street Bullies in his first NHL game.

And he wouldn’t be entirely stretching the truth.

Called up from the Hershey Bears on Wednesday when Michal Neuvirth fell ill, Grubauer thought his first NHL game would consist of opening an closing the door on the Capitals’ bench.

But after the Flyers took a 4-0 lead on an unscreened slapshot by Max Talbot with 5:05 remaining in the second period, Capitals coach Adam Oates replaced Braden Holtby with Grubauer, giving him his first taste of NHL action.

“It was a dream come true,” said Grubauer, a 21-year-old native of Rosenheim, Germany who was taken by the Caps in the fourth round of the 2010 draft. “I dreamed about this since I started playing hockey.

“It was amazing. I tried to step up and give those guys confidence and show the organization that I can do something as well.”

Grubauer was greeted by a flurry of chances by the Flyers, stopping Sean Couturier in the slot and a pair of chances by Simon Gagne at the side of the net. He ended the night with a perfect 14 saves on 14 shots.

“He did a great job,” Oates said. “It was a tough situation.”

Right wing Joel Ward, who scored the Caps’ only goal in the 4-1 loss, agreed.

“We’ve seen him before,” Ward said. “He had a big exhibition game with us in Columbus; he’s a good goalie. It was good for him to get in the game and gain some confidence.”
