Brazil's João Fonseca becomes first player born in 2006 to win ATP Tour match at Rio Open

RIO DE JANEIRO (AP) — João Fonseca became the first player born in 2006 to win an ATP tour-level match when the 17-year-old Brazilian beat seventh-seeded Arthur Fils 6-0, 6-4 at the Rio Open on Wednesday.

Fonseca defeated the No. 36-ranked Frenchman in front of raucous fans at the clay court tournament in Rio de Janeiro. He knelt on the court in tears to celebrate.

"This is where I belong. I want to be in these huge stadiums," said Fonseca, who won the US Open boys singles title last year. "Now it is all about focusing on the process."

His opponent in the round of 16 will be Cristian Garin of Chile.

Fonseca's victory brought some new energy for local fans, who saw three of the title favorites crash out Tuesday.
