Chicago: Nick Leddy scored 2:45 into overtime and the Chicago Blackhawks improved to 6-0 — the best start in franchise history — with a 2-1 win over the Detroit Red Wings in ice hockey action on Sunday night.

After taking a cross-ice pass from Viktor Stalberg, Leddy fired from the left circle and beat Detroit goalie Jimmy Howard with a shot that slipped just under his glove. Detroit’s Johan Franzen connected early in the third to tie the game at 1 and set up overtime.

Duncan Keith scored a power-play goal in the first period for Chicago, and Corey Crawford finished with 29 saves in his fifth start in six games.

Howard, who has started all five of Detroit’s games, made 25 saves.

The Blackhawks started 5-0 in 1971-72 — Hall of Famer Bobby Hull’s final season in Chicago — and matched it on Saturday night with a 3-2 win in Columbus.

Joe Pavelski had two goals, Patrick Marleau scored again — though only once — and the Sharks stayed undefeated. Joe Thornton also scored for the Sharks, who improved to 5-0-0. Antti Niemi made 23 saves as coach Todd McLellan earned his 200th career victory.

Marleau scored two goals in each of the first four games of the season, becoming the first NHL player do pull of that trick since 1917.

Alexandre Burrows scored for the Canucks, who had a three-game unbeaten streak end. Cory Schneider also stopped 23 shots.

Ryan Clowe tied a Sharks record with eight penalties, all in the first two periods, and a career-high 35 penalty minutes. The game became feisty even before the drop of the puck as Clowe and Burrows got into it at centre ice and it remained that way.
