The Rush were playing less than 24 hours after beating the Mammoth in Denver Friday night.
Robert Church, Ryan Keenan, Mark Matthews and Ben McIntosh all struck twice for the Rush (7-1). Mike Messenger also chipped in and Tyler Carlson stopped 39 shots.
Logan Schuss led Vancouver (1-7) with four goals and Joel McCready added a pair. Rhys Duch, Brandon Goodwin and Tony Malcom had the others.
Eric Penney kicked out 39-of-50 shots in defeat.
Saskatchewan converted on all three of its power play chances while the Stealth were 2 for 4.
“There was only 15 minutes and I thought we emptied the tank,” said Rush GM/head coach Derek Keenan, whose team went directly to the arena after landing at home. “I thought we looked tired in the third, but we found our legs in the fourth. Carlson did, the defence did and they blocked a lot of shots. (Mike) Messenger and (Chris) Corbeil had a big effort working hard on a loose ball in the corner at the end. That’s the price you have to pay to get a win.”
The two teams will face each other again next weekend as they clash meet up in Vancouver for the rematch next Saturday night.
