Click to view Champions Spotlight Write UP Mililani dominated the OIA Division I bracket, outscoring opponents 33-3 with two mercy-rule wins on the way to the championship. The Trojans' lineup has teeth. Koa Marzo came in as a Hawaii recruit and carried that momentum, Jonah Parker, Knox Marzo, and senior Taye Marxen all did damage in the postseason. The order's got depth and balance. Where Mililani really stands out is on the mound. Zayne Hookala and Ezra Ugale are two quality arms that can work deep into games when it matters. The Trojans allowed three runs total across three games, including back-to-back shutouts. Freshman Ajay Moss also ate up quality innings and is another piece of the strong pitching staff of Mililani. Mililani heads into states with a complete picture. Offensive output, shutdown pitching, and the depth on the bench to stay fresh.

Good looking swing from Marzo here. Turns this one around for a hard hit RBI knock to left. Versatile athlete with a confident presence in the box. #beseen @B_HarrisonPBR | @MililaniTrojans @Koa_MarzoJr pic.twitter.com/0nRXtKkfYZ
