The event which was set to take place between May 3-10 2020 has been cancelled; it will not be rescheduled joining big tournaments such as Indian Wells and Miami in recent times to be cancelled.
In a statement below, this has been done due to the fact that the tennis season will be suspended until at least 7 June 2020 meaning it is not feasible for them to run the tournament.
With Roland Garros now shifted towards the end of the year, the first action we could have back will potentially be Queens Club and Wimbledon; before shifting into the Hard Court swing and the former major on the clay.
