William Nylander scored on a penalty shot 6 seconds into overtime to lift the Maple Leafs to a 3-2 win over the sagging Chicago Blackhawks.
Nylander was awarded the attempt after he broke in alone on Jeff Glass from the opening faceoff in the extra period, but was hooked from behind by Chicago's Duncan Keith.
Nylander scored the game-winner and his 10th goal by faking Glass and then burying a high backhander to send the Blackhawks to their fourth straight defeat.
Toronto's Nazem Kadri connected for his 15th goal, a power-play score that snapped a seven-game scoring drought and was just his second goal in 20 games. Mitch Marner also scored for the Leafs, who won for the second time in seven games.
Brent Seabrook and Nick Schmaltz scored power-play goals for Chicago, which snapped an 0-for-16 drought with the man advantage.
Toronto's Frederik Andersen made 34 saves. Glass finished with 33.
