Washington didn't get off a shot on its power play, either.
The Capitals outshot New York 13-10 during a scoreless first period in which Washington had the lone power play. Lundqvist denied Marcus Johansson on a shot from the low end of the right circle with just over 13 minutes elapsed, and seconds later Ovechkin was leveled by Staal after unleashing a wrist shot from the left circle.
New York's first power play provided the game's initial goal. With Brooks Laich off for hooking, Rangers defenseman Michael Del Zotto took a shot from the left circle that hit Carlson and Washington's Matt Hendricks. Callahan was in position to sweep the bouncing puck into the right side of the net.
Washington killed 27 of 30 penalties in the postseason before Callahan's goal. It was bad omen for the Capitals, who were 5-1 in the playoffs when scoring first and 0-3 when falling behind 1-0.
Carlson tied it at 11:10, deftly skating from left to right around three Rangers in the New York zone before launching a wrist shot that whizzed past Lundqvist's right shoulder into the top of the net. Stralman got caught up ice, and Carlson skated around Gaborik to get free.
