Dutch Junior Open Geschiedenis

Mr van Keeken, former head of the Economic Department of the local hospital Duin en Bosch, laid the foundation for TC Bakkum in 1926 on a concrete surface near the hospital. The TC Bakkum foundation he founded was initially intended for hospital employees who played tennis for fun. However, Van Keeken developed his ambition for tennis, especially when it comes to juniors. Until 1953, in which he died, as district head and head of juniors of the KNLTB, he was the great stimulator of tennis within the Kennemerland district. In this part of the Netherlands he is seen as ‘the soul of tennis’.

The van Keeken tournament

In 1956, on behalf of the then mayor of Castricum, C.F. Smeets, the name of the tournament changed to the W.E. van Keeken tournament. At the fall meeting of 1964, the tournament was changed to a complete junior tournament. In the beginning, Henk and Frans Wegdam led the tournament with great enthusiasm. In 1975, Brenda van Keeken, granddaughter of our founder, took over the management of the tournament from the Wegdam brothers. As a competitive player and chairman of Popeye Goldstar in Amsterdam, Brenda van Keeken was very well connected and the tournament soon gained national and later international fame.

The guest houses

Over the years, the tournament developed into a household name in Castricum, and also in the wider area, partly due to the phenomenon of ‘host families’. All participating juniors were accommodated with host families. For the young top players, this felt like a week ‘at home’. This is an unforgettable experience for both players and host families. The host families are strongly involved in the tournament and you often see them encouraging ‘their’ players. That creates a beautiful atmosphere!

The staff

Since 2015, the name of the tournament has been changed to ‘Dutch Junior Open’. The staff has approximately 25 enthusiastic TC Bakkum members, all of whom are connected to the club in one way or another. They organize the most important and largest international junior tennis tournament in the Netherlands.


Since 1998, the tournament has been classified as ITF category II. From 2023 this will be called a J-200 tournament). With this classification, the Dutch Junior Open is the highest rated and only J-200 tournament under 18 years held in the Netherlands. J-200 means that the tournament is one of the top 25 youth tournaments in the world. The Dutch Junior Open, together with the Wimbledon youth tournament and tournaments in Germany and Switzerland, forms a strong European youth circuit and therefore attracts participants from the top 100 of the ITF youth rankings every year. Every year, approximately 200 participants from 35 different countries around the world register for our tournament. Naturally, many Dutch players, including part of the KNLTB selection, also registered.
