Del Norte closed to within 40-29 at the end of the third. Rek-Woi Alameda drove left for two for Del Norte before Henry Turner had a bucket inside to stop the Del Norte run. With 5:27 to go at a timeout, Del Norte had pulled within 42-34, and would continue to creep back. But a Douglass three late was a killer for the Warriors, and Mack hit free throws late to account for the 49-42 final. Del Norte would host Eureka on Friday at 7:30 p.m.Ken McCanless can be reached at 707-441-0526.
