Ashley Grossman scored the go-ahead goal in the first overtime period and the second-ranked Stanford women's water polo downed host USC, 12-9, in a Mountain Pacific Sports Federation opening contest Sunday.
A fourth-quarter rally by USC forced overtime as the Cardinal (1-0, 14-1) led by as many as four goals in the contest.
USC goalie Victória Chamorro made two saves in the final minute, one on a great backhanded shot by Grossman with one minute to play and the other on a quick shot off an exclusion call with 10 seconds left. Stanford forced USC into a long pass with 30 seconds to go that resulted in a turnover.
Stanford's defense led the way in the extra period, not allowing any good looks and the offense capitalized on scoring opportunities.
Maggie Steffens found Grossman through a tight window as the shot clock winded down for the first goal. Then Stanford displayed a terrific passing sequence that set up Kiley Neushul for an open shot on goal for the second score of the first overtime period.
In the second three-minute overtime period, the only goal came from Jamie Neushul, as she took a pass from her sister Kiley and found the back of the net.
Jamie Neushul led all scorers with three goals, while Grossman, Kiley Neushul and Steffens each scored twice. Gabby Stone was tremendous in goal with nine saves.
Stanford will have a 12-day break before their next match as they focus on finals for the Winter quarter. The Cardinal will be back in the pool on Friday, March 20 when they host Harvard at 7 p.m. in the Avery Aquatic Center.
