The Pittsburgh Penguins closed to within two points of division leaders the New York Rangers with a 6-1 rout on Wednesday.
Pittsburgh avenged a 5-2 reverse on Monday in stunning style, denying the Rangers a shot on goal for nearly 24 minutes as Sidney Crosby, Scott Wilson, Conor Sheary, Phil Kessel and Matt Cullen found the net.
Alex Ovechkin was one of the stars of the day, hitting a hat-trick as the Washington Capitals edged past the St. Louis Blues 4-3 at Verizon Center.
Meanwhile, Cory Schneider was the New Jersey Devils' shootout hero as they came from behind to beat the Toronto Maple Leafs and preserve their unbeaten home record.
CROSBY CLASS, LIMP LUNDQVIST
The Penguins fell behind to a Rick Nash power-play goal in the first period at Madison Square Garden but responded in style in the second.
Henrik Lundqvist allowed four goals from seven shots to hand the Stanley Cup holders a firm advantage, after Matt Murray made a string of fine saves in the opposite goal, including one piece of brilliance to deny Nick Holden.
Crosby finished with three points, including two goals, to move to an NHL-best 14.
DEVILS DEFIANCE CONTINUES
Three shootout saves from Schneider proved decisive as the Devils extended their unbeaten home run with a 5-4 win over the Maple Leafs.
Jacob Josefson scored in the second round after Schneider stopped Auston Matthews, Mitchell Marner and Nikita Soshnikov.
With a 7-0-1 record at Prudential Center, the Devils are the only side without a regulation loss at home this season.
