For it to be a real Battle of the Sexes, the court dimensions have to be the same and it has to be tennis. It could be one set, but it has to be two serves. The court size has to be the same because that's the way tennis is played. Is this more of an exhibition and is Kyrgios going to take her along or is it going to be a real battle out there where they go toe-to-toe properly? We don't know.
