On April 17, 2018, Young and the rest of Sanity, except for Nikki Cross, were drafted to the SmackDown brand as part of the Superstar Shake-up. They debuted on the June 19 episode of "SmackDown Live", where they attacked The Usos (Jey Uso and Jimmy Uso). The next week on "SmackDown Live", Young made his main roster in-ring debut by answered United States Champion Jeff Hardy's open challenge, which he won by disqualification after The Usos ran in, leading to a six-man tag team match, where Sanity lost. At Extreme Rules, Sanity defeated The New Day (Big E, Kofi Kingston, and Xavier Woods) in a tables match. At Survivor Series, they made up part of Team SmackDown as they took on Team Raw, and they would go on to win the match, although they were eliminated from match. On the April 2, 2019 episode of "SmackDown Live", Sanity lost to The Miz in a handicap falls count anywhere match, in what would be their final match as a stable. A WWE.com article blamed their lack of success on "SmackDown" on being "in the same division as The New Day, The Usos, The Bar, and The Bludgeon Brothers."
