The New York Rangers, Pittsburgh Penguins and Boston Bruins have all regained the home-ice advantage in the NHL playoffs.

Judging by Sunday night's play, however, they may not need it.Those teams all won road games to take 2-1 leads in their respective series. The Rangers were especially impressive, routing Washington 6-0 at the Capital Centre in the Patrick Division semifinals.

Action in the Campbell Conference continues tonight with Chicago at Minnesota and St. Louis at Detroit in the Norris playoffs and Los Angeles at Vancouver and Calgary at Edmonton in the Smythe. All the series are tied 1-1.

Patrick Division

Rangers 6, Capitals 0

Mike Richter had 37 saves in his first NHL shutout and Bernie Nicholls had two goals and two assists to spark the Rangers.

Richter, who had gone 76 games without a shutout, was seriously tested on only a few occasions - the last time a blast from the crease by Tim Bergland with three minutes left. He has allowed only three goals in playing all three playoff games.

Penguins 4, Devils 3

The Penguins beat New Jersey on a bizarre goal by Mark Recchi with 50 seconds left after Devils defenseman Eric Weinrich botched a bloop pass in his zone.

Weinrich was in the low slot when he failed to handle the puck, which was flipped into the air by Phil Bourque from center ice. Weinrich wanted to glove the puck as it came down, but he missed it and then knocked it with his stick toward goalie Chris Terreri.

Recchi, streaking down the middle of the ice, lunged at the puck with his stick and it went between Terreri's legs for the game-winner and Recchi's second goal of the game.

Adams Division

Sabres 5, Canadiens 4

Defenseman Mike Ramsey's soft shot beat Patrick Roy to snap a tie and give the Sabres their victory over Montreal. Ramsey moved in from the point to take a pass from Rob Ray before drifting a 12-footer over Roy at 2:28 of the third period.

Tony Tanti, Christian Ruuttu, Benoit Hogue and Grant Ledyard also scored for Buffalo.

Bruins 6, Whalers 3

Dave Christian and Garry Galley scored 18 seconds apart to spark a four-goal third period as Boston beat Hartford.

Bob Sweeney added a goal three minutes later for Boston and Craig Janney had a goal on a two-man advantage. Ray Bourque and Glen Wesley also had power-play goals for the Bruins.
