Why Finn Bálor Was Moved to WWE SmackDown

TLDR

According to Dave Meltzer on Wrestling Observer Radio, WWE moved Finn Bálor to SmackDown to separate him from Dominik Mysterio and JD McDonagh after their recent feud on RAW concluded with Bálor's victory over McDonagh on May 18. Meltzer explained that WWE wanted to give Bálor a fresh start and avoid continued interactions with former Judgment Day members, similar to how they previously separated Rey Mysterio and Dominik Mysterio after their storyline ended. Bálor's trade to SmackDown was officially announced on the June 1 episode of RAW, and he is now scheduled to compete in a Fatal 4-Way match against Royce Keys, LA Knight, and Jey Uso in the King of the Ring tournament.
