Frisian handball

Frisian handball (West Frisian: keatsen; Dutch: kaatsen) is a traditional Frisian sport, related to American handball and fives, that is most commonly practiced by people from the northern Dutch province of Friesland (Fryslân). It is believed to be one of the oldest ballgames and was an unofficial demonstration sport at the 1928 Summer Olympics in Amsterdam. The scoring is similar to tennis. The first team scoring six games wins the match.
