TOP DOG
Davis of Yakima is the only team in the classification that has not lost to a school from Washington, and that includes wins over reigning Class 4A champion Camas, GSHL winner Union, 4A NPSL champion Tahoma and District 6 powers Mead and Kamiakin.
CAN FILL IT UP
Right now, Union junior Brooklynn Haywood is the most challenging guard assignment in Washington. She can get a shot off against anybody - at any distance. Close to 2,000 career points, she is on pace to break Hailey Van Lith's state-record career scoring mark (2,994 points).
CAN'T-MISS MATCHUP
For two teams that have not played very often, Davis of Yakima and Sumner don't care much for each other, especially after their tension-filled WIAA tournament game last season for third place. State's best sophomores - Sumner's Kawehi Bornd and Davis' Cheyenne Hull - go at it.
GAME PICKS
Davis of Yakima over Sumner

Chiawana over Auburn

Mead over Eastmont
