Game 2 goes Wednesday in Vegas before the best-of-seven series switches to Washington for Games 3 and 4.

"I never saw it coming", Marchessault said. We know what type of player he is out there. "They're guys that work hard every game, every practice".

But Karlsson jammed in his seventh shortside with 1:41 to send the teams to the locker rooms tied 2-2 following a frenetic opening 20 minutes.
