Reid Duke had a pair of goals for Brandon including a power-play goal with 2:29 left that snapped a 3-3 tie.
"It sure felt like a playoff game, as do all the games down the stretch usually feel like," said Duke on CKLQ's post-game show, "This was a really big game for us to come out on top of."
Jayce Hawryluk continued his hot streak with a goal and two assists, with his goal tying the game 3-3 at the 13:35 mark of the third period.
Brandon felt a 1-0 lead after the first period on a power-play goal from rookie Stelio Mattheos, and extended that lead to 2-0 four minutes in the second period on Duke's first of the game.
Moose Jaw tied the contest with back-to-back goals during delayed Brandon penalties, with Dryden Hunt notching his 51st of the year and Brett Howden tying the contest with 4 1/2 minutes left in the middle frame.
Hunt gave the Warriors their first lead of the game with a power-play goal four minutes into the third period, setting the stage for a Wheat Kings' comeback victory.
"I thought we did deserve to win, and yet when you trail late in the third, there's no guarantees that you're going to get in done," said Brandon GM/Coach Kelly McCrimmon, "Some real clutch plays by our club."
Duncan Campbell and Nolan Patrick also scored for Brandon, with Patrick's empty-net goal giving the sophmore centre goals in 14 of his last 15 games and 39 on the season.
Duke became the third Wheat Kings' player to hit the 30-goal mark on the season in Friday's contest.
"Felt nice to have a big game. It was time for me to step up," said Duke, "Some of those goals were the benefit of some hard-working play by my linemates. Getting 30 goals is a big reflection on the guys that I'm playing with as well."
The victory allowed the Wheat Kings to remain tied with Lethbridge for first-place in the Eastern Conference.
Brandon will visit the Moose Jaw on Saturday night (6:35 p.m., 880 CKLQ).
