Former US Open champion Juan Martin del Potro has returned but lost his opening court after two-and-a-half-year break due to injury – and he doesn’t know if he will play again.
The Argentine was defeated 6-1 and 6-3 by compatriot Federico Delbonis at the Argentine Open.
Del Potro, 33, cried at the end of the match and had to be comforted by Delbonis after the defeat.
“Possibly we may not meet again,” he told the Buenos Aires crowd.
“I will speak to doctors again. I have to take care of my knee and then we will see,” he said.
“If today was the last time, I will leave happy.”
The former world No. 3 has not played since breaking his knee at Queen’s in 2019 and undergoing multiple surgeries to repair it.
He previously spoke of his home tournament as an opportunity to say goodbye to his fans, although he also intended to play next week’s Rio Open in Brazil.
