Senators 5, Blue Jackets 2: Clarke MacArthur scored twice and added an assist as host Ottawa used a third-period outburst to upend Columbus.

Captain Erik Karlsson recorded a goal and an assist while Zack Smith and Alex Chiasson also tallied for the Senators, who used three goals in a 7:27 span of the third to pull away. Kyle Turris added a pair of assists while Robin Lehner posted a sensational 36-save performance.

Defenseman David Savard and Cam Atkinson tallied for the Blue Jackets, who have dropped three in a row. Curtis McElhinney stopped 29 shots in his first start of the season as Columbus placed Sergei Bobrovsky on injured reserve earlier in the day with a fractured finger.

Savard opened the scoring in the dying seconds of a power play, skating in uncontested and slapping a shot past Lehner from the left faceoff circle at 5:19 of the first period. MacArthur evened things with a man advantage just over a minute later, redirecting Karlsson's point shot past McElhinney's left pad.

Smith's deflection of defenseman Cody Ceci's shot eluded McElhinney at 1:44 of the middle session, but Atkinson drew the Blue Jackets even with 1:03 remaining in the period with a one-timer. Karlsson put the Senators in front early in the third, jumping into the rush and wristing a pass by Turris from the slot past McElhinney, and Chiasson put away the game near the midway point of the period with a power-play goal.
