UNDATED (AP) — The Anaheim Ducks have regained sole possession of first place in the NHL's Western Conference by winning for the 14th time in their last 15 games.

Mathieu Perreault scored twice and four other Ducks had two points in a 5-2 triumph over Boston. Perreault, Corey Perry and Nick Bonino scored power-play goals, and Andrew Cogliano added a short-handed tally that put Anaheim ahead 3-0 late in the second period.

The outcome puts the Ducks two points ahead of Chicago in the West and leaves the Bruins seven points behind the East-leading Penguins.

Pittsburgh trailed 4-2 late in regulation before winning for the 17th time in 20 games, 5-4 in a shootout at Vancouver. Sidney Crosby tied the game with 55 seconds left in the third period before netting the lone shootout goal. Kris Letang (leh-TANG') ignited the comeback by scoring with 1:11 left, 16 seconds before Crosby's goal.
