Hockinson led by 13 after the first quarter but Ridgefield rallied to tie the game in the second half.
Payton Wangler was double-teamed on the final play, she found McGuire, who attacked down the lane and was fouled as the horn sounded.

Grace Russell led all scorers with 15 points for the Hawks. She also had four steals and five boards.
