Just when it looked as though the women’s lacrosse team was going to have a disappointing record in Ancient Eight competition, it reached a dramatic turning point. If there was one victory that could make up for Cornell’s less-than-satisfying performance in the first half of the season, it was a win over Princeton on Easter Weekend. The Red (3-6, 2-2 Ivy) defeated the No. 17 Tigers (4-6, 2-1 Ivy), 11-8, in Princeton, N.J., on Saturday to at last gain bragging rights after a long and winless history against its conference rival.
