With both original host schools eliminated from postseason play, the 4A and 3A softball regionals will be held Saturday at Columbia Playfield in Richland.
Four Tri-City schools remain in contention for state berths: Richland in 4A and Kamiakin, Southridge and Kennewick in 3A. Walla Walla is the 4A regional's top seed from the CBBN.
The 4A regional originally was scheduled to be played at Larson Playfield in Moses Lake, while the 3A tournament was set for West Valley High School in Yakima. However, Moses Lake was eliminated from districts last weekend, and Kennewick ousted West Valley in a loser-out game Thursday.
Regional play begins at 1 p.m. Saturday with two loser-out games in each tournament. The 4A and 3A championship games are scheduled for 5 p.m.
