Bruins 3, Flyers 2 (OT): Brad Marchand converted on the power play with 15 seconds remaining in the third period before scoring 3:52 into overtime as host Boston continued its dominance of Philadelphia.

With Wayne Simmonds serving a tripping penalty, Marchand extended his stick to deflect home defenseman Dougie Hamilton's shot from the point to forge a 2-2 tie. Tuukka Rask denied Jakub Voracek on a breakaway late in overtime and Marchand secured the win by skating across the slot and beating Steve Mason for his team-leading 21st goal.

Captain Zdeno Chara also scored a power-play goal for the Bruins, who completed a three-game season sweep of the Flyers and are 17-3-1 in the last 21 meetings - including playoffs. Hamilton notched two assists and Rask finished with 29 saves.

Voracek scored with the man advantage to reach the 20-goal plateau for the third straight season, but the Flyers suffered their 12th loss in their last 15 road contests (3-8-4). Chris VandeVelde also tallied and Mason turned aside 34 shots as Philadelphia fell five points behind Boston for the second wild-card spot in the Eastern Conference.

Entering the contest mired in a 4-for-32 stretch on the power play, Boston scored first for the seventh straight game as Chara's wrist shot from the point beat a screened Mason at 7:07 of the first period. Voracek answered from the right faceoff circle midway into the second and Philadelphia claimed a 2-1 lead with 4 1/2 minutes left in the third as VandeVelde deflected defenseman Nick Schultz's shot from the point for his first goal since Feb. 5.
