Purdue transfer Mason Gillis, the Big Ten Sixth Man of the Year, joined Duke after helping the Boilermakers reach the national title game earlier this month.

Gillis made the announcement via Instagram on Monday.

Gillis gives head coach Jon Scheyer and Duke an addition to the roster after seven players entered the transfer portal following the NCAA Tournament.

The 6-foot-6 forward was previously a starter before coming off the bench for Matt Painter in all 39 games in 2023-24. Gillis shot 46.8 percent from 3-point range, averaging 6.5 points and 3.9 rebounds per game.

With 132 career games at Purdue, Gillis is considered a graduate student with one year of eligibility remaining.
