The ABN AMRO World Tennis Tournament, or currently called Rotterdam Open, is an ATP event played in indoor hard courts. This event is held annually in Rotterdam, Netherlands at Rotterdam Ahoy. This tournament was attended by Roger Federer, where he became a champion holder in 2005, 2012, and 2018. Federer and Arthur Ashe are the only players who hold the most titles in the tournament.

The Foundation of the ABN AMRO World Tennis Tournament
The first edition of the ABN AMRO World Tennis Tournament was held in November 1972, where Arthur Ashe was hailed champion. The following year, the organization decided to move the tournament to March, however, this was not well-accepted by the tennis community. The ABN AMRO World Tennis Tournament was supposed to be a part of the World Championship in 1978, however, in 1990, the management decided to make it part of the ATP Tour.
One of the most unforgettable moments in Rotterdam Open is when the match of Ivan Lendl and Jimmy Connors was interrupted by a false bomb alarm. The match was not finished because of it, and Lendl has to give up the match because he wasn’t prepared to play.
