>>Alex Ovechkin Scores 500th Career Goal

Alex Ovechkin's status among the greatest goal scorers of his or any generation in the NHL was never in question, but now the Great 8 has achieved one of the iconic milestones in the game. The Washington Capitals captain scored his 500th NHL goal Sunday against the Ottawa Senators.

It came like so many others before it. Ovechkin set himself up inside the left faceoff circle on the power play. Long-time teammate Jason Chimera passed the puck through a group of Senators penalty killers and hit the captain on the tape. Ovechkin had plenty of space and let it rip. The puck soared past Sens goalie Andrew Hammond and set off the celebration.

Ovechkin was mobbed by his teammates, all of them including those that were previously on the bench. Even goalie Braden Holtby, who was backing up was on the ice to join in the group hug.

Ovechkin took a curtain call, waving to the home crowd at Verizon Center.

Ovechkin is the 43rd player overall and one of just six players in the history of the NHL to reach the 500-goal mark before his 31st birthday.
