Rio Open presented by Claro is the first ATP World Tour 500 tournament in Brazilian history and was the first WTA tournament held in Rio de Janeiro. It is part of a selected group of thirteen tournaments named ATP 500, and one of the 22 biggest events in the ATP calendar. It is also the most important annual sporting event in the city, and one of the few ATP 500 tournaments played on clay, along with Barcelona and Hamburg.

Some of the greatest stars in the sport were part of the tournament: Spaniards Rafael Nadal, 2014 champion and global icon, 2015 champion David Ferrer and Tommy Robredo, Frenchman Jo-Wilfried Tsonga, Austrian Dominic Thiem, American John Isner and Italian Fabio Fognini. Among the ladies, we have had the presence of Italians Sara Errani, 2015 champion, and Francesca Schiavone, Roland Garros champion and winner of Rio Open in 2016.

In addition to the matches and practice sessions in nine clay courts, including the Center Court with a 6,200-seat capacity, we have Leblon Boulevard, an area with stands, stores and food courts for the audience.

The biggest tournament in South America received 45,000 spectators in 2016 at the Jockey Club Brasileiro. They watched 92 tennis matches played by 94 athletes from 31 countries.

Starting in 2017, Rio Open became an ATP-only tournament. It was a strategic decision by IMM and the Instituto Carioca de Tênis to provide more comfort for both athletes and audience. The fourth edition on the tournament was evaluated as the best of the history of Rio Open by the ATP. 45,000 people attended the Jockey Club Brasileiro. The singles champion was Austrian Dominic Thiem, another top 10 player to win in Rio. Spaniard Pablo Carreno Busta and Uruguayan Pablo Cuevas won the doubles title.

The fifth edition of Rio Open presented by Claro will happen from February 19th to the 25th. Defending champion Dominic Thiem, Croat Marin Cilic and Frenchman Gael Monfils have confirmed their entry in the main draw, alongside Pablo Carreno Busta, Pablo Cuevas, Fabio Fognini and Kyle Edmund.
