Thompson’s 35th goal of the season put the Sabres in front 3-2 at 1:23 of the third. Zach Benson won a battle behind the net before sending a backhand pass to Thompson, who snuck it under Anton Forsberg ’s right arm from alone in front.

Tage Thompson scored the go-ahead goal 1:23 into the third period, and Lindy Ruff became the NHL’s second coach to win 600 games with one franchise in the Buffalo Sabres’ 3-2 win over the Ottawa Senators.

Ruff is in the first season of his second stint in Buffalo, and improved his record with the franchise to 600-467-90 with 78 ties. Ruff trails only Al Arbor, who won 740 games with the New York Islanders.
