Waiakea senior Jazz Alston usually serves background music on the volleyball court, functioning as a mobile blocker and down-the-list offensive option.
But she made the loudest noise and powered Waiakea over Kamehameha 25-22, 18-25, 25-18, 25-21 in the BIIF Division I semifinals on Tuesday night at the Warriors Gym, where long rallies and loads of energy came along for the ride.
In the other Division I semifinal, Hilo defeated Kealakehe 20-25, 25-21, 25-14, 25-17 at the Vikings Gym, eliminating the Waveriders.
That locked up an HHSAA tournament berth for Waiakea (15-2), which plays Hilo (16-1) for the BIIF Division I title at 7 p.
