One Championship, the premier Singaporean martial arts promotion, has been making moves in the grappling world. In March 2021, the organization announced that it had signed Gordon Ryan, the consensus pound for pound best submission grappler on the planet. The organization had already signed Ryan’s teammate Garry Tonon back in 2017, following a grappling match with jiu-jitsu black belt and MMA veteran Shinya Aoki in 2016. Other recent additions to the One roster include Tom DeBlass, Andre Galvao, and Danielle Kelly, as part of the push to put on submission grappling matches along side MMA and kickboxing fights.
One announced on Sunday that they had signed the Ruotolo brothers.
