Richter, the Game 3 loser with a sub-par performance, out-dueled Chris Terreri this time as the Rangers beat the Devils 3-0 to tie their best-of-seven series at 2-2.
The teams will resume the series with Game 5 at Madison Square Garden on tomorrow night.
The only scores of Game 4 came on third-period goals by Jan Erixon, Paul Broten and Mike Gartner. And that was more than enough for Richter on this night.
He was clearly sharper than in Thursday night's 3-1 loss, making 33 saves in a peerless performance. It was Richter's second playoff shutout of his career and saved the Rangers the ignominy of going back to New York down 3-1 to the underdog Devils, who finished 18 points behind the Patrick Division winners and NHL regular-season champs.
The game was virtually non-stop from start to finish and finally decided in the last 16 minutes on the goals by Erixon and 'D Broten, who are not known for their scoring.
First Erixon broke the scoreless tie with a 15-footer from the slot after taking a pass from Mark Messiser, who was being checked into the right boards by Viacheslav Fetisov.
Erixon's goal was only his seventh in nine seasons of playoffs.
Then Broten sewed it up when he beat Terreri between the pads at 8:29 from the left circle. Broten, who had only one previous playoff goal, picked up the puck in the Rangers zone and carried it in himself.
?3 Gartner added an empty-net goal with 1:09 left.
Ted Donto's second goalf of the series 2:08 into overtime gave Boston a victory over Buffalo and a 3-1 lead in their Adams Division semifinals.
