Brent Seabrook scored on a 2-on-1 break at 3:23 of overtime and the Chicago Blackhawks extended their NHL-record, season-opening point streak to 21 games with a 4-3 win over the Columbus Blue Jackets on Friday night.
Jonathan Toews carried the puck down left wing and dished a cross-ice pass to Seabrook, who fired in a shot from the right circle before goalie Steve Mason could slide across the crease.
Patrick Sharp and Bryan Bickell scored 59 seconds apart late in the second period, and Viktor Stalberg also connected in regulation for Chicago (18-0-3), which won its eighth straight overall and has earned 39 out of a possible 42 points this season.
Ray Emery made 19 saves for the win.
Ryan Johansen scored with 7:37 left in regulation to tie it at 3 for Columbus, snapping his 37-game goal drought.
