Only one more game separates WIAA state-championship hopefuls from the destination spot for Class 4A basketball: Tacoma Dome.

Starting Friday, 16 teams play in the regional round of the WIAA playoffs – with 12 schools advancing to the state tournament in Tacoma.

Here is the Class 4A regional boys basketball primer:

TOP DOG

Richland lost its only game in the final minute of the District 6 championship game at Gonzaga Prep – and dropped to the No. 4 seed. No squad in the tournament has the offensive firepower the Bombers boast – and now they have motivation to show who is boss.

CAN FILL IT UP

The list of guards with career games of 40 or more points is impressive: Jo Lee, of Glacier Peak; Landen Birley, of West Valley of Yakima; Landen Northrop, of Richland; Cesar Hernandez, of Davis of Yakima; and Leyton Martin, of Arlington. All can go off at any time.

CAN’T-MISS MATCHUP

Is Gonzaga Prep vulnerable as a 1-seed? Bullpups are as well-coached a team as there is in Washington, but face 4A SPSL champion Puyallup that has skill, height and good guard play, led by league MVP Drew Jones.
