COLUMBUS, Ohio — Kevin Connauton had a goal and two assists, and the Columbus Blue Jackets scored four times in the second period for a 6-2 win against the Boston Bruins on Saturday night.

Scott Hartnell, in his first game back after missing five games with a broken finger, scored the Blue Jackets’ first two goals for a 2-1 lead early in the second. Nick Foligno and Connauton made it 4-1 before Craig Cunningham scored for the Bruins (18-15-3). Matt Calvert regained the three-goal lead with 51 seconds left in the second.

Jeremy Morin added a goal for Columbus in the third.

Patrice Bergeron scored in the first period for the Bruins, 20 seconds after Hartnell had given the Blue Jackets (15-16-3) a 1-0 advantage.

Columbus backup goalie Curtis McElhinney made 26 saves. He replaced Sergei Bobrovsky, who did not play because of a stomach virus. Boston backup Niklas Svedberg stopped 12 of 15 shots before being pulled for Tuukka Rask, who also had 12 saves.

Hartnell scored his first goal on a rebound of a Connauton shot that Svedberg took off his shoulder. Hartnell put a backhander off the inside of Svedberg’s pads at 8:11.

The Bruins came back with Bergeron, who has seven goals, stickhandling around Columbus defenseman Fedor Tyutin, then getting a wrist shot past McElhinney.

Hartnell, who has eight goals, made it 2-1 in the second with a redirect of Connauton’s shot from the left point 51 seconds into the period.

Connauton upped the score to 3-1 at 6:32 with his fourth goal in 14 games since being claimed off waivers Nov. 18 from the Dallas Stars.

Foligno followed at 9:26 by converting a pass from Jack Johnson during a Columbus power play for a 4-1 lead. Foligno’s 17 goals are one shy of his career best, which he set in 70 games last season.

Cunningham cut the deficit in half with 3:32 remaining after a shot from the right blue line by Gregory Campbell. The puck hit Cunningham in front, then went off Johnson for Cunningham’s second goal.

Calvert capped the second-period scoring with an unassisted goal. Morin scored his first goal early in the third period.
