Alex Killorn scored 1:50 into overtime to lift the Tampa Bay Lightning to a come-from-behind 3-2 victory over the winless Buffalo Sabres on Tuesday night.
Teddy Purcell, with the tying goal 5:43 into the third period, and Tyler Johnson also scored for the Lightning (2-1), who have two wins after regulation.
Tampa Bay has yet to hold a lead in regulation after coming off a 3-2 shootout victory at Chicago in which the Lightning overcame a 2-0 third-period deficit.
Jamie McBain and Cody Hodgson had a goal and assist each for Buffalo (0-3-1).
Despite the loss, Buffalo finally generated some offense by doubling its season goal total. And the Sabres also earned a point to avoid extending their franchise-worst season-opening losing streak to four games.
Buffalo had previously never lost more than two straight in regulation.
