RIO DE JANEIRO — Second-seeded Casper Ruud of Norway pulled out of the Rio Open clay-court tournament on Thursday with an abdominal injury.
Ruud told a news conference that he was still feeling the effects of an injury he picked up during Sunday’s final of the Argentina Open, which he won.
“I tried as much as I could, but unfortunately it wasn’t possible,” Ruud said. “It was a tough decision, I was looking forward to play here.”
Ruud was replaced by Spain’s Roberto Carballes Baena, who lost his second-round match against Argentina’s Francisco Cerundolo 6-3, 6-2 after the second set was halted for a rain delay.
Cerundolo will next face Serbia’s Miomir Kecmanovic, who beat sixth-seeded Lorenzo Sonego of Italy 7-5, 6-4.
Top-seeded Matteo Berrettini of Italy was set to play Brazil’s Thiago Monteiro later.
