Lehtonen denied all three Sabres shootout attempts and stopped 32 shots overall in a 5-4 win Saturday night, ending Buffalo's season-opening winning streak at 10. The Sabres will settle for sharing the league record for best start to a season set by Toronto in 1993.
Former Sabres player, Vyachelsav Kozlov, scored the only shootout goal the Thrashers needed, beating Ryan Miller with a snap shot inside the left post.
The loss - the Sabres' first in the regular season since a 4-2 defeat to Philadelphia on April 7 - also ended their 15-game winning streak over two seasons, two short of the NHL record set by Pittsburgh in 1993.
It wasn't for a lack of trying. Buffalo rallied four times from one-goal deficits, with Jochen Hecht tying the game with 1:44 left in regulation.
