BOSTON (AP) - Nathan Horton broke a tie midway through the third period with his fourth goal in four games and the Boston Bruins beat the Ottawa Senators 3-2 with an aggressive attack that produced a season-high 50 shots Tuesday night.
While awaiting the arrival of newly acquired five-time NHL scoring leader Jaromir Jagr from the Dallas Stars, the Bruins shook off their recent offensive woes with their second straight win after losing five of their previous seven games.
Horton got his 12th goal of the season at 10:21 of the third period after goalie Robin Lehner stopped Milan Lucic's shot with his pad. But Horton scored on the rebound.
The Bruins held a 50-47 advantage in shots on goal. Their previous high of 46 came on Feb. 28, also against the Senators, in a 2-1 overtime win in Boston.
The Bruins outshot the Senators 21-19 in the first period, their most shots in a period since they had 22 on Feb. 19, 2012 at Minnesota.
The pace slowed for a while in the third period after Andre Benoit tied the score 2-2 with 1:55 gone following an officials' review. Play had continued after Benoit's hard, high shot. At the next whistle, officials ruled that the puck had gone in just under the crossbar then come out, resulting in Benoit's third goal of the season.
Colin Greening had given Ottawa a 1-0 lead 2:48 into the game before goals by David Krejci and Tyler Seguin 1:01 apart put Boston ahead 2-1 at 4:29 of the first period.
Earlier Tuesday, the Bruins obtained Jagr for prospects Lane MacDermid and Cody Payne, both forwards, and a conditional second-round pick in this year's draft that becomes a first-rounder if the Bruins reach the Eastern Conference finals.
Jagr is expected to join the Bruins in time for Thursday night's home game against New Jersey.
Greening started the scoring on Tuesday when he took a loose puck in the slot and backhanded it between goalie Anton Khudobin's legs. It was Greening's seventh goal of the season and third in four games.
But less than two minutes later, Boston had the lead.
Just 30 seconds after Greening's goal, Krejci got his ninth for the Bruins when he deflected Zdeno Chara's shot from the blue line past Lehner.
And 61 seconds after Krejci scored, Seguin gave Boston a 2-1 lead with his 12th goal of the season but only his second in eight games. Brad Marchand passed the puck across the slot from the left side and Seguin put it in the right side of the net that Lehner had left open when he skated toward Marchand.
Zdeno Chara put the puck in the net for Boston at 12:11 of the first period, but the goal was waved off because Patrice Bergeron was in the crease.
NOTES: The Bruins scored in the first period for the first time in eight games. ...

The game began a season-high seven-game road trip for the Senators. ... The Bruins are 22-1-0 when allowing two or fewer goals
