During the Baskèts Open there is plenty of room for recreational players to play tennis, but also for them, just like for the participants in the ‘Pro League’, the referees are of the highest national level. During the final of the ‘Pro League’, there is another gear. While one of the referees climbs into the chair, the others assume their position as line judges. And picking up balls is no longer an option for the finalists, because in this case the ‘ball kids’ are present for that. Although there are no ‘kids’ alone, this job is done by a number of friendly and extremely charming young ladies. Ladies who also fully enjoy the relaxed atmosphere and cheerfully party during the live performance of the singer.
