Marvin Castelle may have locked up Submission of the Year after this past weekend. The BJJ brown belt must’ve saw the helicopter armbar by Diego Brandao and decided to one up the Brazilian.

Competing in the Fight to Win Pro event on Friday evening, Castelle nailed a perfect Imanari Roll to secure a takedown directly into a leg lock. Castelle and his opponent Darby Faulkner would fight for position but ultimately, Faulkner ceded and tapped out.

Marvin Castelle. NASTY.

Safe to say Submission of the Year is Castelle’s to lose at this point.
