Top-seeded San Ramon Valley features junior Kat Klass and freshman Sarah Klass. They are the daughters of former Stanford All-American Craig Klass, a member of the U.S. Olympic men's water polo team in 1988 (earning a silver medal) and '92. He is a member of the USA Water Polo Hall of Fame.
Second-seeded Campolindo features Natalie Seidemann. She is the younger sister of recent Stanford grad Melissa, who won a gold medal on the U.S. women's team at the 2012 London Games.
Klass and Seidemann were teammates this summer on the U.S. Women's Youth National Team that won a gold medal at the UANA Youth Pan American Games in Buenos Aires, Argentina. In a 23-4 semifinal win over Puerto Rico, Klass scored five goals and Seidemann added four.
This season, the Klass sisters have helped San Ramon Valley compile a 20-0 record. The Wolves have beaten nine of the teams in the 16-team NorCal event, including Campolindo and Sacred Heart Prep twice each.
"Kat Klass is a great athlete and dynamic scorer," said SHP coach Jon Burke. "If you stop her one way from scoring, she'll quickly find another way. We would like to play them again this weekend, but will have to get through two games prior to having that opportunity."
Sacred Heart Prep (15-5), which dropped 14-5 and 10-8 decisions to SRV, is seeded No. 4 and is in the Wolves' bracket. The two could meet in one semifinal on Saturday in the Gators' Dunlevie Aquatic Center at 11:10 a.m. The championship match is set for 5 p.m.
Sacred Heart Prep opens against No. 13 Rio Americano on Friday at 1:05 p.m.
Opening at Menlo-Atherton High on Friday will be the Bears and Gunn. M-A, seeded No. 15, takes on Campolindo at noon, followed by No. 10 Gunn against No. 7 Miramonte.
