A Kailua, Hawai'I native, Harrison was a standout at Punahou High School where he was a three-year letter winner, two-time team captain and State Tournament MVP. With a successful high school career under his belt, he brought his skills to the mainland and impressively started all 56 games at shortstop for the Texas A&M Aggies in 2021. He flashed major leather that year, leading the squad in assists and is back at the position this year looking to improve on an impressive freshman season. Harrison comes from a baseball family, with older brother KJ (Brewers 3rd round pick out of Oregon State in 2017), and younger brother Kaikea (senior shortstop at Punahou HS and A&M commit).
