RIO DE JANEIRO (AP) -- Rising Austrian star Dominic Thiem reached the quarterfinals of the Rio Open on Wednesday with a 7-5, 7-5 victory over Argentina's Diego Schwartzman.
The fifth-seeded Thiem, the youngest player in the ATP's top 20 at age 22, was about the only bright spot on a rain-soaked day that saw the match between No. 2 seed David Ferrer and fellow Spaniard Albert Ramos-Vinolas rained out.
Much of the rest of the playing schedule was also washed out in the third straight day of rain in Rio de Janeiro.
Third-seeded Jo-Wilfried Tsonga of France got in his first-round match early, but was beaten 6-3, 3-6, 6-4 by Brazilian Thiago Monteiro.
