Craig Simpson, Terry Ruskowski and Mike Bullard scored goals to lead the Pittsburgh Penguins over the Minnesota North Stars last night, 3-2. With the home victory, the Penguins extended their unbeaten streak to 3-0-1 while stopping Minnesota's 3-0-1 run.

At 21-20-5, the Penguins climbed above .500 for the first time since Oct. 31, 1984, when they had a record of 5-4-0.

Bullard scored the eventual game-winner at 2:48 of the third period. Mike Blaisdell's right wing pass deflected off Bullard's skate for his 25th goal of the season and a 3-1 lead.

Goalie Roberto Romano had 31 saves and was working on a shutout until the third period.

Romano is 14-10-2 and has the most wins by a Penguins goaltender since Michel Dion's 25 in the 1981-82 season. He and veteran Gilles Meloche are playing on a regular rotation system.

"They basically know they're going to play every second game and they're able to prepare for it," Pittsburgh Coach Bob Berry said. "Romano's played extremely well, but I think overall we've probably played a little bit better in front of the goaltenders." Sabres 6, Devils 3
