McGrath initially rose to prominence in 2015 after placing highly in several major tournaments.[3][4] Among his best placings are first at GENESIS 5, second at The Big House 7 and Smash Summit 9, and third at EVO 2016 and EVO 2018. McGrath was initially the best Samus player in the world but later switched to primarily playing Sheik. In addition to playing Samus and Sheik, McGrath uses Fox as a secondary. McGrath has also competed professionally in Super Smash Bros. Ultimate, playing primarily with Mega Man and Ridley, and Project M playing primarily with Samus. McGrath was formerly sponsored by Panda Global.[5] A 2021 list compiled by PGstats ranked McGrath as the tenth-greatest Melee player of all time.[6]
