Ovechkin started the attack with a wrist shot that flew over the head of Flyers goaltender Brian Elliott. The puck slid around the boards to Capitals defenseman Dmitry Orlov, who threw a shot at the Flyers' netminder.
Elliott deflected the shot and Ovechkin grabbed the rebound near the crease. The Capitals star was tripped as he smoothly shifted the puck through two Flyers defenders.
