Memphis clearly out-classed its weaker, seventh-seeded opponent by grabbing a 21-6 advantage and never letting up.
During the opening Memphis surge, Tulsa made only one of 10 shots and faced a 42-13 hole at halftime.
The top-seeded Tigers, playing the event at FedEx Arena, their home court, grabbed their third straight tournament title.
A big factor was Memphis making 11 of 22 three-pointers.
Jerome Jordan led Tulsa (20-13) with 17 points and nine rebounds.
Ben Uzoh had 13 points and three rebounds for the Golden Hurricane, which had recorded back-to-back overtime victories over Alabama-Birmingham and Texas-El Paso to get to the final.
