Diggins, a South Bend native, and fellow senior Kaila Turner have led the Irish to a school record 121 victories in their four years at Notre Dame and back-to-back national championship game appearances.
Playing on the same court that the Notre Dame men's team beat Louisville 104-101 in five overtimes back in February, the Irish didn't lead in overtime until Kaila Turner hit a free throw early in the third to put the Notre Dame ahead 82-81.
