The Amsterdam Masters Open (AMO, formerly known as ASIO) is an ITF senior tournament for men and women from age 30 till 90+. We offer single, doubles and mixed doubles. Doubles and mixed doubles should preferably be arranged when entering the tournament, but it is possible to enter doubles on the spot.

The tournament is part of the ITF Masters Circuit, so it is possible to earn points for your ranking in the world. For entry you will need an IPIN.

A grade 700 ITF Masters Tournament

Our regulars probably still remember the first edition of the Amsterdam Senior International Open in Nieuw-Vennep.  There were still a lot of challenges: which location, who are going to participate, how can we schedule the matches best? Essential elements for a successful week!

In our second year we moved closer to Amsterdam, to our present venue.  Within a few years we reached a grade 2 status, which we were very proud of. Due to construction work at the venue we had to cancel our 2018 edition. But we came back stronger. Our 2019 edition was held at a completely renovated National Tennis Center. This was also the first edition we’ve organized with a grade 1 status! In 2020 we had to cancel again, now because of Covid, but in 2021 we decided against all odds to pick it up again, with a very gratifying attendance as result. In 2023 we reached a peak with over 200 participants from 27 countries.

Our tournament is known for its friendly atmosphere, beautiful venue and strong competition. And this is how we want it to be. We continue to strive for the ideal mix of top tennis and socializing. Besides the matches we hope to organize a great Players Dinner. Sightseeing in Amsterdam for our contestants from abroad is only a bus ride away.

Will we see you at this years’ edition?
