Kevin Stevens scored twice and referee Bill McCreary nullified an apparent game-tying goal Saturday night as the Pittsburgh Penguins forced a seventh game in the Patrick Division semifinal by defeating the New Jersey Devils 4-3.

The deciding game will be played Monday night in Pittsburgh with the winner advancing to the division championship against Washington. The Capitals eliminated the New York Rangers on Saturday night.New Jersey had hoped to avoid the trip to Pittsburgh and might have had McCreary not waved off a goal by Laurie Boschman with 1:32 left in the second period, which would have tied the game 4-4.

But McCreary ruled that Boschman directed the puck past Frank Pietrangelo with his skate. The replay showed he deflected the pass by Claude Lemieux with his stick and then it went off his stake.

Pietrangelo, subbing for the injured Tom Barrasso and making his first playoff appearance, made the lead stand up thereafter, making 28 saves.

The Penguins came into the game facing elimination and knowing they would be without both defenseman Paul Coffey (scratched cornea) and Barrasso (shoulder injury).

The Penguins line of Francis, Stevens and Recchi accounted for three goals and five assists.
