And now it's double overtime, for the first time in any game this postseason.
The Rangers' best chance was broken up by referee Paul Devorsky, who ran into Brandon Dubinsky as he and Marian Gaborik were headed for 2-on-0 thanks to a terrible Caps line change.
There's no doubt that the Rangers look tentatived as the overtime began. Eventually tentative gave way to tired, and tired gave way to overmatched.
The first overtime saw Lundqvist make his biggest save of the series, a glove stop on Alex Ovechkin on a clean breakaway with 8:58 to go. It was Henrik's 40th save.
Other than that save, the biggest moment of the first overtime came when the Caps got a free power play when Derek Stepan flipped the puck over the boards. Dan Girardi blocked shots by Ovechkin and Alex Semin and the Rangers killed it off.
After that, the Rangers just hung on. Semin knocked down a clearing pass and the Caps swarmed for a good 30 seconds in the Rangers end, and the Caps continued to apply pressure as the overtime ended.
With the shock of blowing a three-goal lead now behind them, the Rangers will have to come out more determined to play aggressively and get a forecheck going, something they did not do at all in the last 20 minutes. Otherwise, they'll just be relying on a fluke goal or a bad line change.
