It was the first win for Buffalo since a 4-1 victory at New Jersey on Feb. 23, and ended an 0-15-3 streak. The Sabres also snapped a 0-9-2 home skid, one short of matching a franchise record set during the 1990-91 season. After Philadelphia’s Ivan Provorov scored 3:50 into the second period, Buffalo responded by closing the period with goals from Fogarty and Casey Mittelstadt.
