グレート・アメリカン・バッシュ
The next week, Booker entered a battle royal on "SmackDown!" with the winner to challenge Rey Mysterio for his World Heavyweight Championship at The Great American Bash. Booker won the battle royal and then defeated Mysterio at The Great American Bash to win the World Heavyweight Championship after Chavo Guerrero betrayed Mysterio by hitting him with a steel chair. This was Booker's first world championship since joining WWE and the win caused him to proclaim himself as the "King of the World". This win would also make Booker the sixteenth Triple Crown Champion and eighth Grand Slam Champion (under the original format) in the history of the WWE.
