COLUMBUS -- The Columbus Blue Jackets' best offseason move continued to pay dividends when forward Sam Gagner had two goals and two assists in a 4-1 win against the Arizona Coyotes at Nationwide Arena on Monday.
Gagner, who was an unrestricted free agent, signed a one-year, $650,000 contract on Aug. 1 with hopes of resurrecting his career. He had eight goals in 53 games for the Philadelphia Flyers last season and also spent time in the American Hockey League.

But Gagner is tied with Nick Foligno for the Blue Jackets lead with 10 goals and has seven assists in 23 games.
"I'm happy for him because he knew when we were talking this summer that this was a chance, probably his last one, to stay in the League," Columbus coach John Tortorella said. "He's been a huge addition to our team."

The Blue Jackets (15-5-4) are 5-0-1 in the past six games.
Tobias Rieder scored on the power play for the Coyotes (8-12-4), who have lost four in a row. Louis Domingue made 30 saves.
"We were all right," Coyotes coach Dave Tippett said. "Penalties caught up with us and we didn't create enough offense to overcome it."
Foligno and rookie defenseman Zach Werenski also scored and Cam Atkinson had two assists. Sergei Bobrovsky made 17 saves.
Rieder put the Coyotes up 1-0 at 9:28 of the first, scoring his seventh goal.
Columbus has the top-ranked power play in the NHL (.246) and scored its first two goals with the man-advantage Monday. The Blue Jackets are 12-for-36 (.333) at home on the power play.
Gagner, who played for the Coyotes in 2014-15, tied the game 1-1 on the Blue Jackets' first power play at 11:39 and Foligno gave Columbus a 2-1 lead early in the second period.
"We were a little sluggish early," Gagner said. "Our power play kept us going. We were moving the puck around pretty good and were able to get a couple there, which is nice."
Gagner's goal at 11:37 of the third gave Columbus a 3-1 lead. Brandon Saad assisted for his 200th NHL point. Gagner then assisted on Werenski's sixth goal at 15:00.

Unsung moment of the game
Goligoski prevented Columbus from taking a 2-1 lead during its power play with eight minutes left in the first period when he swept the puck off the goal line after a tipped shot by Boone Jenner got behind Domingue.
