RIO DE JANEIRO (AP) — Three-time major winner Stan Wawrinka was eliminated from the Rio Open on Tuesday, beaten 7-5, 6-4 in the first round by Argentina’s Facundo Díaz Acosta.
The 23-year-old Díaz Acosta won his first title on Sunday at the Argentina Open.
The clay-court match was delayed for almost two hours due to rain in Rio de Janeiro. Diaz Acosta’s next opponent will be his compatriot Sebastián Báez.
The 38-year-old Wawrinka won the 2014 Australian Open, 2015 French Open and 2016 U.S. Open, where he defeated the world No. 1 player in the final on all three occasions.
Díaz Acosta played in Argentina as a wild-card entry with a career-high ranking of 87. He rose to No. 59 on Monday.
“I had to have a lot of patience because of the rain,” Díaz Acosta said. “Stan is a legend, it was amazing to play against him.”
Later on Tuesday, No. 2-ranked Carlos Alcaraz was scheduled to play Brazil’s Thiago Monteiro.
