With Nashville a man down after a high-sticking penalty, Patrick Kane sent a pass across the ice to Hossa, who one-timed it past the goaltender for his 17th goal of the season.
Elsewhere, St.Louis moved within a point of third place in the Western Conference with a win over Dallas, while Calgary won its final home game of the regular season by downing Anaheim.
