COLUMBUS, Ohio - Christian Backman scored at 1:33 of overtime, Dan LaCosta made 28 saves in his first NHL start and the Columbus Blue Jackets beat the San Jose Sharks 3-2 on Saturday night to end a three-game losing streak.
Backman, a defenceman, jammed home the puck from near the goal-line for his second of the season after a shot by R.J. Umberger crawled past Evgeni Nabokov.
San Jose's Christian Ehrhoff floated the puck from the left point past LaCosta - screened by two players - to tie it at two with 3:58 remaining.
The Western Conference-leading Sharks have lost a season-high three straight games.
Jason Williams and Rick Nash also scored for Columbus, who recalled LaCosta on Friday on an emergency basis with starter Steve Mason - second in the NHL with a 2.09 goals-against average - sidelined by mononucleosis, and recently acquired backup Wade Dubliewicz out with the flu after losing 4-1 at Pittsburgh on Friday night.
A third-round pick in 2004, LaCosta's only NHL game action was in two relief appearances. He allowed a combined two goals on 24 shots.
Ehrhoff had a goal and assist, and Devin Setoguchi also scored for San Jose.
Facing the task of beating the best team in the Western Conference and sporting the league's fourth highest-scoring offence, Columbus started fast and efficient.
The Blue Jackets scored on their first two shots to give LaCosta an early 2-0 cushion after the opening period.
Williams stole a clearing pass in the right slot from defenceman Alexei Semenov and roofed Columbus' first shot over the glove hand of Nabokov, who dropped to 27-6-6, at 1:46 for his 10th.
Nash took a breakaway pass from Kristian Huselius across the Sharks blue-line and beat an outstretched Nabokov with a low shot, just the Blue Jackets' second, at 9:33 for his 23rd and first in five games.
Umberger nearly scored late in the period on Columbus' third shot, but he couldn't convert on the short-handed breakaway.
Setoguchi put San Jose on the board 54 seconds into the second period, wristing a shot alone in the slot for his 22nd, a power-play goal, and his first since Jan. 20.
