Watch: Gostisbehere bomb opens scoring in Flyers must-win game

Shayne Gostisbehere's first career playoff goal may prove to be the best birthday gift ever.

The Philadelphia Flyers defenseman - who turned 23 years old Wednesday - one-timed a shot from the point early in the first period of Game 4 to give his club a 1-0 lead.

The goal was mighty clutch as the Flyers are in win or go home mode.

It was extra fitting the goal came on the power play since the Washington Capitals have torched the Flyers for eight power-play goals of their own in the series.
