Tayla Stuttley had 24 points but missed two free throws late setting the stage for Steiner's game-winning hoop.
"I saw Dessa was pretty closely guarded so I thought I should cut in there and she happened to find me and gave me a really good pass. I knew I had to shoot it because I didn't have very much time and I was just praying it went in and it did," said Steiner.
Steiner finished with 16 points while freshman Lexi Donarski led Aquinas with 18.
Aquinas stayed undefeated.
