Prosser sewed up the No. 1 seed and a bye into the state playoffs.
The CWAC No. 2 seed also gets a bye into the state playoffs, but that team is up in the air between Othello and Ellensburg.
Those two teams meet Thursday, Nov. 3, in Othello.
Selah and East Valley, which are tied for fourth, also play Nov. 3 in a game that could decide the final CWAC playoff spot.
