Tim McGauley and Jayce Hawryluk had a goal and an assist each for Brandon while Reid Duke added three assists for the Wheat Kings.
Brandon was sluggish over the final 40 minutes after jumping out to the huge lead, but Duke said on CKLQ's post-game show that the win was the important thing.
"We did come out with the two points," said Duke, "We definitely didn't play the way we thought we should have but, at the end of the day, it's a win and, hopefully, we can just lead into (Saturday) night's game."
Duke, a sixth round pick of Minnesota in the 2014 NHL Draft, now has 14 points (5 G, 9 A) in the last nine games and is one of eight Wheat Kings' players averaging better than a point per game.
"At the beginning, it kind of took a while to settle in," said Duke, "With the team that I had, and now a team getting wins, it's somewhat hard to explain."
Peter Quenneville, John Quenneville, Jesse Gabrielle and Braylon Shmyr also scored for the Wheat Kings while Jordan Papirny made 46 saves in the Brandon net including 19 in the third period.
Brett Stovin and Amil Krupic did the goal scoring for Saskatoon with Alex Moodie and Trevor Martin combining for 30 saves in the Blades' net.
The victory improved Brandon's Eastern Conference-leading record to 15-3-1-0 and maintained their four-point lead over the second-place Medicine Hat Tigers.
The Wheat Kings are back on home ice on Saturday, hosting the Calgary Hitmen (7:30 p.m., Westman Communications Group Place).
