Dennis Seidenberg scored the tiebreaking goal on a slap shot from center ice in the third period, rallying the Boston Bruins to a 4-3 win over the Ottawa Senators on Tuesday night.
Brad Marchand and Zdeno Chara had power-play goals and Chara also had an assist for the Bruins, who fell behind 3-1 while being dominated in the second period.
Milan Lucic's goal with 45 seconds left in the second got the Bruins within one and Marchand's power-play goal 2:20 into the third tied it.
Seidenberg put Boston ahead with 12:51 remaining as he stepped into a low shot just after crossing the red line and the puck whistled untouched between Craig Anderson's blocker and the post.
Tim Thomas made 30 saves for Boston, which allowed 10 goals in its last two games heading into the All-Star break. Thomas settled down after the Senators scored three straight for a 3-1 lead.
Anderson finished with 26 saves. He couldn't control a rebound and Marchand whacked at it until it went in for the tying goal, then was stunned by Seidenberg's blast from the Bruins' logo a few minutes later.
The Senators have lost four straight — all on the road after setting a franchise record with a point in 11 straight road games.
The Senators controlled the second period, playing like they were on a power play for most of it even though they never had a man advantage. Ottawa outshot Boston 13-5 in the period and got goals from Kyle Turris and Erik Karlsson to take a 3-1 lead.
Turris fired an unscreened shot past Thomas with 12:17 left in the second for a 2-1 lead. Karlsson put Ottawa up by two with a wrist shot from the left circle that also got past Thomas.
Boston finally broke Ottawa's grip on the period in the final minute and Lucic took advantage on a shot from the slot that got Boston within 3-2 with 45 seconds left.
Ottawa got a late goal when Colin Greening one-timed a pass from Milan Michalek in the slot. Michalek got the puck after Filip Kuba's blast from the point hit Thomas hard in the left pad and the rebound bounced right to Michalek at the right circle.
Boston had taken a 1-0 lead on Chara's slap shot from the point on a power play, his first goal in 17 games — not counting his goal Sunday in the All-Star Game while leading Team Chara to victory.
