Sam Reinhart scored the deciding goal to lead the Sabres to a 4-3 win over the St. Louis Blues on Sunday. It came moments after his backhand chance struck the post with less than a second remaining in overtime.
It resulted in Buffalo's first win since March 1, and Buffalo's third win in its past 16 games.
Johan Larsson, Evan Rodrigues and Conor Sheary scored in regulation for the Sabres. Carter Hutton made 30 saves.
After Jack Eichel and Tyler Bozak traded goals to open the shootout, Reinhart scored on Buffalo's final attempt. Reinhart's wrist shot had just enough to get past St. Louis goalie Jake Allen, who got a piece of the shot with his glove.
Former Sabres center Ryan O'Reilly then had a chance to extend the shootout, but his backhand chance hit the crossbar.
Pat Maroon, David Perron and Brayden Schenn scored for the Blues, who remain in the thick of the Western Conference playoff race with 82 points (37-27-8). Allen made 31 saves.
It marked the end of an ultimately disappointing road trip for St. Louis. On Saturday, the Blues dominated the surging Pittsburgh Penguins with a 5-1 win - but that was surrounded by defeats to struggling teams like Ottawa and Buffalo.
The Blues return home against Edmonton on Tuesday.
