Porter announced his verbal commitment via Twitter.
Porter was expected to go to Washington last season, but when the staff was fired, he opted to open up his recruitment and follow his father to Missouri.
A five-star forward, Porter is currently regarded as the No. 5 player in the 2017 class, but is expected to rise when Scout releases their final player rankings.
Porter helped lead Nathan Hale to a 3A state title this past season, averaging 37 points and just over 14 rebounds a game.
