The Buffalo Sabres opened their preseason schedule with a 4-3 overtime win over the Washington Capitals on Sunday afternoon. Dylan Cozens, Tyson Kozak and Jack Quinn scored for Buffalo in regulation, before Vinnie Hinostroza potted the game-winner 1:15 into the extra frame. The teams also went through a practice shootout - each team is allowed to do that twice in the preseason - and the Sabres won that, too.
