The Capitals were 20 minutes away from heading home with the series tied 2-2. They now have at least 20 more minutes to change that to 3-1.
Two goals from Marcus Johansson and one from Alexander Semin brought the Caps back from a 3-0 deficit to send Game 4 to overtime tied at 3-3.
Semin gave the Caps life at 2:47 by crashing the net. After Henrik Lundqvist stopped his initial shot, Semin skated to the net and punched the puck in. Lundqvist thought he had the puck under his glove, but he couldn't cover it and Semin took advantage. The referee called it a goal on the ice and the call stood after a review.
Johansson gave the Rangers a taste of their own medicine with a quick goal 57 seconds later. Brooks Laich threw the puck on net and Johansson was in the right place at the right time to deflect the centering pass past Lundqvist for his first career playoff goal. But Johansson wasn't finished. He scored his second of the night at 12:07 to tie the game when a John Carlson slap shot at the end of a power play deflected off of his body and into the net.
Shots were 13-7 in favor of Washington in the third period and are 35-26 in favor of the Caps for the game.
