Beauchamp joined Ignite after playing 12 games with Yakima Valley College, where he averaged 30.7 points, 10.5 rebounds and 4.8 assists while shooting 52.5 percent from the field and 39.8 percent from three-point range. He was the No. 47 prospect in ESPN’s Class of 2020, but opted to train with NBA Draft prep program Chameleon BX, based in the San Francisco Bay Area, after high school. As a prep star, Beauchamp claimed back-to-back state championships, first as a freshman at Nathan Hale High School and then as a sophomore at Garfield High School. As a junior, he led Rainier Beach High School to league and district titles, plus a state semifinal appearance, to be named MVP of the Seattle 3A Metro League. He also earned spots on the USA Today All-USA Washington second team, Associated Press Class 3A All-State first team and the Seattle Times All-State second team. Beauchamp spent his senior season at Dream City Christian in Arizona.
