Lots to like from this athletic LHH SS/MIF who can do a little bit of everything. One of the obvious stand-outs at BIWBA's 2025 Memorial Day Tournament: Powered by Prep Baseball Hawaii, where Uyehara established himself as one of the most advanced 2027's on both sides of the ball. Love the actions at SS, made a highlight play and took some of the better AB's all tournament with some big/clutch hits when his team needed it. Uyehara is one player who Prep Baseball Hawaii feels is on track to be not just a strong DI commit but one of the better players in the 2027 Hawaii class.
