Paul Reinhart scored two power play goals to help Calgary avoid elimination and cut visiting Edmonton's lead to three games to one in the NHL Smythe Division final series.

The Flames, outscored by 21-8 in the first three games, forced the best-of-seven series back to Edmonton for Game 5 Wednesday.

Coming off a 10-2 humiliation Sunday, the Flames checked the Oilers harder and with more effect than at any time in the series. Their power play, a fizzle in the first three games, connected three times--twice with a two-man advantage--to stop Edmonton goaltender Andy Moog's playoff winning streak at six games.

But the Flames barely survived. They held a 6-2 lead at 9:50 of the third period and had to beat back a determined surge in which Edmonton scored three goals, two by Ken Linseman, against goalie Don Edwards in a span of just over seven minutes and had a chance to tie the game on a power play in the last 1:48 of the game.

Wayne Gretzky, who had four goals and three assists Sunday, had the Oilers' second goal last night. graphics/photo: Duane Sutter crashes into Rangers goalie Ed Mio in the first period. UPI
