PHILADELPHIA (AP) – Joni Pitkanen scored the tying goal with 23.4 seconds left and added the winner 1:55 into overtime to give the Philadelphia Flyers a 4-3 victory over the Boston Bruins on Tuesday night.

The Flyers won their fourth straight game and seventh in a row at home, overcoming a two-goal deficit in the final 3:35 of regulation on goals by Pitkanen and Simon Gagne.

Sergei Samsonov, Shawn McEachern and Joe Thornton scored for the Bruins, who haven’t lost in regulation in nine games since Oct. 20.

With goalie Robert Esche on the bench and an extra skater on the ice, Pitkanen took a long pass from Peter Forsberg, streaked down the left side and wristed a shot into the far corner under the crossbar to tie it at 3. In overtime, Pitkanen took a pass from behind the net and tucked it past goalie Hannu Toivonen to win it. Mike Knuble also scored for Philadelphia, which played without captain Keith Primeau and top defenseman Eric Desjardins. Both players have concussions.

Samsonov scored during a two-man advantage 56 seconds into the third to give the Bruins a 2-1 lead. Thornton set it up with a nifty pass in front.

Soon after, Esche made a sliding save with his left pad on a shot by Thornton to keep the deficit at one.

But Thornton scored an unassisted goal to make it 3-1 with 4:48 left. Gagne cut it to 3-2 a minute later with his NHL-leading 16th goal. Boston tied it at 1 on McEachern’s power-play goal late in the second. McEachern’s slap shot sailed past Esche’s glove.

Knuble deflected a slap shot by Kim Johnsson past Toivonen for a power-play goal that gave the Flyers a 1-0 lead in the final minute of the first.

Knuble played his first game against his former teammates. He spent 41/2 years with the Bruins and was a member of Boston’s top line with Thornton and Glen Murray.

Notes: Murray sat out with the flu. … Primeau has missed the last four games, while Desjardins has missed two straight.

… The Bruins are 4-5 in the last nine games, with three losses coming in overtime and two in shootouts. … Forsberg recorded his league-leading 22nd, 23rd and 24th assists. … The Flyers have scored power-play goals in 10 straight games.
