Henrik Lundqvist brought up a milestone win in the NHL, while fellow goaltender Braden Holtby continued his run.
Lundqvist became the 12th goalie in NHL history to win 400 games as the Rangers beat the Colorado Avalanche 4-2 on Saturday.
Holtby, meanwhile, has 14 straight wins after his Washington Capitals edged past the Anaheim Ducks 6-4.
Also extending a winning streak were the St Louis Blues, who recorded their fourth straight victory.
Lundqvist made 32 saves in his and the Rangers' victory.
Kevin Klein scored twice in the win, to go with goals from Rick Nash and Kevin Hayes at Madison Square Garden.
Holtby now has the equal second-longest win streak by a goalie in NHL history.
He made 18 saves in the Capitals' hard-fought win, with Zach Sanford and Marcus Johansson scoring late in the third period.
