The South American clay swing starts here, in the heat of Rio. The Rio Open brings ATP 500 tennis to Brazil for a week of grinding rallies and heavy topspin, where patience often matters more than power.

Sebastian Baez returns as the defending champion on the golden clay. With the Carioca humidity slowing the court further, expect long, physical exchanges from the opening round. The 32-man draw runs 16 to 22 February with $2.3M on the line.
