Underdog St. Ursula then beat the Warriors (19-1-2) in the second round of penalty kicks to take a 1-0 upset victory in the Division I state semifinal played at Tiffin Columbian's Frost-Kalnow Stadium.
Knotted 3-3 after the first round of five penalty kicks for each team, Arrows senior midfielder Kiley Armstrong scored as the second shooter in the second round, and Walsh's Sandra Yu sailed her try over the crossbar to give St. Ursula (15-6-1) the sudden-death win.
