Junior Rachel Ingraffea scored with 13:13 remaining in the half, and senior Rebecca Minaker added another with 10:37 left to give UMass a commanding 6-3 lead.
Minaker's goal would set the stage for Harvard's dramatic comeback and give the Crimson an added boost in confidence heading into its home opener this Wednesday against Boston College.
The Crimson cruised to an easy 14-8 win over B.C. in the opener a year ago with a pair of hat tricks from Corkery and then-freshman Katharine Burrage.
"I'm very confident personally heading into the B.C. game and a lot of the other players feel the same way," Corkery said. "There is just too much depth and talent on the team this year and we are all very hopeful."
