Williamson netted 38 points as he led Spartanburg Day to a 74-41 win over Trinity-Byrnes in the SCISA 2A state championship.
Williamson will play in two high school All Star games, highlighted by the McDonald's All American Game. He will then be on the Duke campus early this summer to prepare for his collegiate career.
The South Carolina native is currently a part of a recruiting class which includes, Cameron Reddish, R.J. Barrett and Tre Jones. And that class may well add another player before the season starts.
