DALY CITY, Calif. (AP) _ Guy Carbonneau scored one minute into overtime to lift the Montreal Canadiens to a 1-0 victory over the San Jose Sharks in a game between the teams with the NHL's best and worst records Saturday night.

Sylvain Lefebvre picked up a loose puck along the right boards and fired a wrist shot that Jeff Hackett stopped with his stick. Mike Keane picked up the rebound at the goal line to the right of the San Jose goal and fed Carbonneau on the doorstep. Carbonneau one-timed a shot past Hackett for the game-winner.

Montreal goaltender Patrick Roy made 25 saves for his fourth shutout of the season in a game that was delayed 55 minutes by an ice problem.

The Adams Division-leading Canadiens improved their record to an NHL-best 27-14-2 for 56 points. The Sharks, last in the Smythe, slumped to 9-29-3 for 21 points.

The two teams played to a scoreless tie through regulation, but Hackett was far busier than Roy in the final period as the Canadiens stormed the San Jose goal. Hackett's pad save with 17:45 to play turned away Denis Savard's backhand from the doorstep at the end of a Montreal 2-on-1.

The San Jose goalie made another pad save two minutes later, stopping Sylvain Turgeon's 35-foot slapshot from the high slot. Hackett made a difficult blocker save on Mathieu Schneider's wrist shot from the slot with six minutes left, and then turned away Stephane Lebeau after Lebeau walked in alone with 3 1-2 minutes remaining.

Roy turned away San Jose's best scoring opportunity of the final period with 5 1-2 minutes to play, stopping Mike Sullivan's wrist shot from the right circle at the end of a 2-on-1 break. He also smothered Pat Falloon's backhand from the left faceoff circle with 1:04 to play.

Montreal outshot the Sharks 20-16 through the first two periods, but the Canadiens had far more quality scoring chances than San Jose did.

Carbonneau said that Brent Gilchrist initiated the play that led to the deciding goal.

''It started at the blue line when Gilchrist broke up the play,'' Carbonneau said. ''I never got a good view of the puck, but I knew the puck was coming on my stick from Keane when I went to the net.''

Hackett said he did not have a chance on the deciding goal.

''I didn't see it. I don't even know where it went,'' he said. ''I just felt it. I just wish it hit me.''

It was a disappointed San Jose locker room, but the Sharks tried to look at the loss positively.

''We have to look at it in a positive light,'' said San Jose defenseman Neil Wilkinson. ''We showed we can play with any team in the league. You hate to lose for Jeff Hackett because he played outstanding. It just didn't work out.''

Roy was quick to point out that the losing goalie had a more difficult night than he did.

''Hackett had to make tougher saves at the other end than I did,'' Roy said.
