Calgary, AB (Sports Network) - Eric Nystrom's second-period goal proved to be the difference, as the Calgary Flames staved off a late San Jose rally to post a 4-3 win over the Sharks at Pengrowth Saddledome.
With the win, Calgary temporarily moved one point ahead of Detroit for the eighth and final playoff spot in the Western Conference. The Red Wings are visiting Edmonton on Friday.
Dany Heatley had the other goal for San Jose, which has lost four in a row -- all in regulation -- on its current six-game road trip. The Sharks, who are winless in five straight overall, have watched their once-sizeable cushion in the Pacific Division standings whittled to a precarious three points by the red-hot Phoenix Coyotes, winners in each of their last seven games.
Evgeni Nabokov stopped 20 shots.
