A two-point basket by Katie Theut helped Aquinas (11-19, 10-12) to its final lead with 57 seconds remaining and set the stage for Tomasik's game-winner.

Tomasik was fouled on her go-ahead shot and then missed the ensuing free throw. Harvey rebounded the basketball, but a SHU turnover/Aquinas steal allowed the hosts one final opportunity with 11 seconds left. Heberlein missed a three-pointer at the buzzer.
