The Flyers reduced the deficit in the best-of-seven series to 3-1, with Game 5 in Boston Monday. The Bruins can clinch their first conference finals since 1992 with a victory.

Gagne got the crowd roaring 3½ hours later on his first goal of the postseason. The Flyers wasted a 3-1 lead and were deflated when Recchi scored the tying goal.
