Melfort chased Survivor Series hero Jack Burgart with three goals in the first four minutes and then hung on to edge Weyburn 4-3 in game one of their quarter-final.
The Mustangs also scored three first period powerplay goals on their way to victory as Adam Fauchoux and Luc Lemire both scored one and set up another.
Rookie defenseman Mike Eskra had a goal and two points to lead the Wings, who came to within one when Braden Mellon scored with just under eight minutes remaining in regulation.
Weyburn, actually, outshot Melfort 20-17 over the final two periods. Game two is Saturday in Weyburn.
