Tajh Ariza is a 6-9 small forward with a 7-foot-plus wingspan, the son of 18-year NBA veteran Trevor Ariza. He attended multiple schools, including Westchester High (his father's alma mater), where he averaged 27 points and 14 rebounds as a junior, earning MaxPreps Junior All-American honors and leading the team to an LA City Section championship. After brief stints at St. John Bosco and Link Academy in Branson, Missouri, for his senior season, Ariza committed to Oregon under coach Dana Altman in October 2025, choosing the Ducks over USC, Arkansas, Kansas, and Arizona.
