Stanford grad Melissa Seidemann scored four goals to help the United States women's water polo team down host China, 16-2, at the Kunshan Cup on Friday.
The Americans (21-2 overall) advance to Saturday's final against Australia, which has a two-match winning streak over Team USA.
Cardinal grad Kiley Neushul and Stanford freshman-to-be Mackenzie Fischer each added a pair. Menlo Park resident and Sacred Heart Prep grad KK Clark also netted a goal, as did Cardinal senior Maggie Steffens.
The Australians have edged the U.S. twice since May 26, both by the score of 5-4, though the Americans won each of the first four matches between the water polo powerhouses this year.
