Smaller Classifications Bring Heart and Hustle

The Class 1A field features some compelling storylines, with top-seeded Zillah High School taking on Chelan at 10:30 a.m. and Lynden Christian High School (No. 2 seed) battling Seattle Christian at 2:00 p.m. These smaller schools represent the backbone of Washington's basketball tradition, where every possession matters and gym crowds bring genuine electricity.
