Aurora Bodenhamer scored two early goals and the Hawks kept their season alive by blanking the Tigers.
Hockinson will play Mark Morris at 1 p.m. Saturday at Battle Ground District Stadium in a winner-to-state match.
Both goals on Thursday came on quick transition attacks. Four minutes in, Michel Berry set up Bodenhamer. Three minutes later Kavita Battan assisted on the second goal.
Hockinson controlled play most of the way, and had 22 shots.
