08/10/2013 - College PREP - Maui, HI Kainalu is a talented, young infielder with good athleticism. He has a loose, quick arm action that is demonstrated in his double play pivot/exchange. Kainalu shows good range and should continue to work on being more fluid during his back hand play to go along with his arm accuracy. At the plate, Kainalu demonstrates good rhythm and balance with a middle of the field approach. He keeps his weight and hands back in sequence while letting the ball travel deep in the hitting zone for success the opposite way. Kainalu has a good swing path which allows for consistent contact. He can be a good hit-and-run type hitter, while continuing to work on keeping hands inside the baseball.
