Auston Matthews had a natural hat trick in the second period and William Nylander scored 54 seconds into overtime to give the Toronto Maple Leafs a 4-3 victory over the Philadelphia Flyers on Thursday night. Matthews pushed his NHL-leading goals total to 45, completing his fifth hat trick of the season and 12th of his career in a 7:49 span in the second period. “Best goal-scorer in the league,” Nylander said.
