Here's a definitive list of all the wins and losses the Capitals have experienced with regard to challenges, referees and the situation room this season.
The Washington Capitals haven't fared too well this season when it comes to goals being taken off the board.
In fact, eight in total have been waved off by the referee, with seven of those coming at the hands of coach's challenges and challenges initiated by the situation room in Toronto itself. Three of those goals belonged to Ovechkin.
Looking at 13 different instances of challenges, referees' decisions and video reviews, Washington has won just two challenges all season long while losing eight goals in total.
Here's a full breakdown of how things have played out this season.
12/30 - Capitals vs. Predators
Who challenged: The situation room
What happened: Alex Ovechkin scored a potential game-winning goal with 59.5 seconds to go in regulation, with Nic Dowd heavily screening Yaroslav Askarov in front. The situation room in Toronto initiated a review due to goaltender interference, and the referees overturned the goal after citing that Dowd's incidental contact impaired Askarov's ability to move in his crease and stop the shot.
Toronto can initiate a review of any goal in the final minute of regulation or at any point in overtime.
Ruling: No goal for Washington.
12/23 - Capitals vs. Lightning
Who challenged: Tampa Bay
What happened: Nick Jensen scored a go-ahead goal in the second period, but the Lightning challenged for offside. It was determined that Joel Edmundson had an offside zone entry on the shift prior to the goal.
Ruling: No goal for Washington.
12/20 - Capitals vs. Islanders
Who challenged: Situation room
What happened: Prior to Dylan Strome's overtime winner, Tom Wilson made contact with the puck up high. It was determined that the puck was not played with a high stick prior to Strome's goal.
Ruling: Good goal for Washington.
