STOCKHOLM -- Mike Hoffman registered two power-play goals and Erik Karlsson added two assists as the Ottawa Senators defeated the Colorado Avalanche 4-3 on Saturday.

Ottawa (8-3-5) won its second straight game to sweep the two-game Global Series. Craig Anderson stopped all eight shots he faced in relief of Mike Condon to earn the win.

Colorado (8-7-1) lost its third straight game, receiving goals from Sven Andrighetto, Alexander Kerfoot and Blake Comeau. Jonathan Bernier made 36 saves.

The Senators staged a two-goal third period rally for the victory. Johnny Oduya's second goal of the season at 7:01 evened the score on assists from Nate Thompson and Jean-Gabriel Pageau. Hoffman gave Ottawa the lead with his sixth goal of the season, unassisted on the power play at 13:23 of the third period. Hoffman gathered in Chris Bigras' failed clearing attempt for a wrist shot that beat Bernier.

The Avalanche took a 1-0 lead on Blake Comeau's shorthanded goal at 13:13 of the first period. Senators defenseman Karlsson was unable to handle Mark Barberio's clearing attempt at the Avalanche blue line. Comeau sped off on a breakaway and beat Condon with a wrist shot to his glove side.

The Senators tied the game on Mike Hoffman's power play goal 13 seconds into the second period. After crossing the blue line, Hoffman lifted the puck into the Colorado zone where it took an odd bounce and squeezed by Bernier with Derick Brassard and Karlsson earning assists.

Colorado regained the lead at 2-1 on a power play goal by Kerfoot, his seventh of the season at 7:36 of the second period. Kerfoot took a return pass from Johnson and beat Condon with a rising wrist shot with Andrighetto earning the secondary assist.

The Senators tied the game 2-2 on Mark Stone's team-leading 12th goal of the season at 9:16 of the second period. Karlsson stole the puck from Matt Nieto inside the Colorado zone and found Stone stationed in front of Bernier for a backhand shot along the ice that found the net.

Colorado took its third lead of the game at 3-2 on Andrighetto's fifth goal of the season at 10:36 of the middle frame. Andrighetto was left unguarded for a wrist shot that deflected off the stick of Ottawa defenseman Dion Phaneuf and by Condon with Kerfoot and Boris Mironov registering assists.
