COLUMBUS, Ohio (AP)—Boone Jenner and Mark Letestu each had a goal and an assist, and Sergei Bobrovsky stopped 31 shots for his second shutout of the week to lead Columbus past the New York Islanders.
The Blue Jackets, desperate to hang on to a playoff spot in the East, matched a season high with three power-play goals.
Jack Johnson and Ryan Murray ended long droughts with goals, and Brandon Dubinsky had two assists. Bobrovsky, who won at Philadelphia 2-0 on Thursday, earned his fifth shutout of the season.
Anders Nilsson made 29 saves for the Islanders, who had their seven-game point streak end.

PENGUINS 3, AVALANCHE 2, SO
DENVER (AP)—Jussi Jokinen skated across the front of the crease and roofed a shot over sprawling goalie Semyon Varlamov to give Pittsburgh a shootout win over Colorado.
After Jokinen's goal, Marc-Andre Fleury made a pad save on Gabriel Landeskog's shot, snapping Colorado's six-game winning streak and denying Varlamov franchise records for most home and overall wins in a season.
After falling behind 2-0 on Brandon Sutter's first multiple-goal game this season, Colorado scored twice in the third period to tie it.
Ryan O'Reilly scored his team-leading 28th goal of the season 18 seconds into the third period, and Patrick Bordeleau redirected defenceman Tyson Barrie's shot from the point past Fleury with 3:13 left in regulation.
Fleury had 39 saves, including one in the closing seconds of overtime.
Locked into the No. 2 seed in the Eastern Conference, the Penguins sat several of their regulars, including Sidney Crosby, who missed his first game of the season because of an unspecified injury.
