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!

The Amsterdam Senior International Open began as an grade 5 tournament. Within a few years we reached a grade 2 status, which we were very proud of. Unfortunately, due to construction work at the location of our tournament we had to cancel our 2018 edition. But we came back stronger. Our 2019 was held at a completely renovated national tennis center. This was also the first edition we’ve organized with a grade 1 status! The 2020 edition we had to cancel because of Covid, but in 2021 we decided against all odds to pick it up again, with a very gratifying attendance as result. In 2022 we maintained that good attendance.

Our tournament is known for its great 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 will organize a great Players Dinner, and – upon request –  a nice sightseeing trip for our contestants from abroad.

Will we see you at this years’ edition?
