Outlook: Just a week after Stanford’s 12-11 double-overtime win over the Trojans, they meet again, because the Pac-12, in its first season of women’s lacrosse, is the only conference in the country in which teams play each other twice. The two are in a three-way tie for first place in the conference with Colorado, which defeated Stanford by two goals and lost to Southern California by one. All three are 4-1. Before falling to Stanford, the Trojans had won 22 consecutive league games, including those from the Mountain Pacific Sports Federation, which included all three teams before the Pac-12. USC hadn’t lost to Stanford in three years. On Sunday, the Cardinal trailed by four goals with 13½ minutes left but rallied to win on Galen Lew’s goal with 23 seconds left in double overtime. Kelsey Murray leads the Cardinal with 26 goals and 22 assists while Kerrigan Miller leads Southern California with 21 goals and five assists. Both teams have Friday games against Pac-12 teams as Stanford travels to Arizona State (6-6, 1-4 conference) and the Trojans host California (4-7, 0-5).
