The Saints were lead by front court players Arsenio Arrington and Opeyemi Sholesi, who had 10 points and 14 points, respectively.
Aquinas led 58-43 in the second half, but SHU cut that deficit down to a single point with less than two minutes remaining.
The Saints went 5 of 6 from the free throw line in the final 62 seconds to seal the win.
Aquinas will hit the road Saturday (Jan. 6) for a 3:00 p.m. game against Concordia in Ann Arbor.
