Hawaii picked up its first senior night win in three years and earned its first 20-win season in a decade with a thrilling 81-77 win over Cal State Fullerton on Saturday at the Stan Sheriff Center.

Point guard Keith Shamburger helped secure the win by going 12-for-14 at the free-throw line in the final minutes, including two with 4.1 seconds left for a four-point lead to ice the victory.

A “White-out” crowd of about 7,500 helped send off seniors Christian Standhardinger, Brandon Spearman and Davis Rozitis as winners in their final game at the Sheriff.
