Grace O'Hara scored late in the third overtime to give number seven Pittsford Mendon a 1-0 win over 10th seeded Aquinas.

Goalies Hope McGuckin (Pittsford Mendon) and Lea Annechino (Aquinas) and their defenders putting up clean sheets until Rachel Renzi hit O'Hara at the top of the box. Her shot inside the right post propelled the Vikings (9-7-1) into the Class A quarterfinals.

The Vikings face second-seeded Mercy, a 1-0 winner over Canandaigua in the first round. That game is at Mercy on Saturday.
