AJ Styles wins United States Championship from Kevin Owens at Madison Square Garden Live Event
NEW YORK CITY — AJ Styles sent shockwaves through the WWE Universe tonight, as he defeated Kevin Owens to become United States Champion during a WWE Live Event at New York City's Madison Square Garden.
The Phenomenal One won the Independence Day Battle Royal on this past Tuesday's SmackDown LIVE, earning a title opportunity against Owens at WWE Battleground, but apparently couldn't wait to get his hands on The Prizefighter.
