Sebastian Wilkins grew up in Boston, Massachusetts, where basketball is both a city sport and a community bond. His father signed him up for a youth league when he was four years old, and the game took hold immediately. Boston’s grassroots basketball scene is tight-knit and fiercely competitive — the kind of environment where kids play against each other in high-intensity summer tournaments and then support each other afterward. Wilkins thrived in that culture from the start.
He enrolled at Lawrence Academy in Groton, Massachusetts, for his freshman year and immediately made an impact. Over two seasons, he earned All-NEPSAC honors and eclipsed the 1,000-point mark before the end of his sophomore year — a remarkable feat that put him on the national radar. His first Division I offer came from Rutgers in September of his sophomore year, followed quickly by Providence and UMass. The recruiting world was starting to pay attention.
After two dominant years at Lawrence, Wilkins transferred to Brewster Academy in Wolfeboro, New Hampshire — one of the premier prep basketball programs in the country, a pipeline that has produced NBA talent for years. Under coach Jason Smith, Wilkins’s game took another leap. He evolved from an interior-oriented forward into a modern combo forward who could shoot the three, handle the ball, attack closeouts, and defend multiple positions. At the Hoophall Classic — the most prestigious high school basketball showcase in New England — he scored 20 points to lead Brewster past Oak Hill Academy and was named game MVP.
On the grassroots circuit with the Mass Rivals on the Adidas 3SSB, Wilkins averaged 16.4 points and 6.1 rebounds during the spring circuit, playing up against older competition as a 15-year-old — a Mass Rivals tradition that accelerated his development. His AAU career included playing alongside future high-major talents like Andre Mills, Kur Teng, Dwayne Aristode, Bryce Dortch, and George Turkson. Mass Rivals director Vin Pastore watched the transformation firsthand and described it as meteoric, noting that Wilkins went from a player people didn’t know to a top-50 national recruit through relentless work.
In his final prep season at Brewster, Wilkins led the Bobcats to the semifinals of the Chipotle Nationals, scoring 22 points and grabbing 13 rebounds in a first-round win before falling to top-seeded Christopher Columbus — featuring his future Duke teammates Cameron and Cayden Boozer — on a buzzer-beater. Even in the loss, Wilkins led all scorers with 14 points and hauled in a game-high 12 rebounds, including seven on the offensive glass. He was named to the EYBL All-Scholastic First Team, a capstone to his prep career.
Wilkins had originally been ranked in the Class of 2026, but his coaches believed he was ready. Duke offered him on April 18, 2025, and he committed on May 23, choosing the Blue Devils over Maryland and reclassifying into the 2025 class. The decision fulfilled a dream that started when he was six years old. He later told ESPN the origin story: watching Zion Williamson play against Tacko Fall in the 2019 NCAA Tournament, turning to his mother, and knowing Duke was the place. His mom took him to visit the campus. The seed was planted. Fourteen years later, he’s there.
