Juan Martin del Potro backed Nicolas Almagro to fight his way back to fitness after the Spaniard was left in tears following his injury-enforced withdrawal from the French Open.
Thursday's second-round clash was curtailed by a knee problem for Almagro which left him unable to continue when the match was tied at one set each.
Del Potro, who revealed he had been struggling with a slight groin issue, consoled his stricken rival, who slumped to the floor in clear distress.
And the 2009 US Open champion was saddened by Almagro's plight, having suffered a few injuries himself.
"It's an unpleasant feeling. You have a player who is suffering quite a lot. He was in agony. It was tough," said the Argentinian, who tried to offer some words of comfort to the three-time Roland Garros quarter-finalist.
"I told him that tennis is important, but health matters more than tennis in this case, because I want him to be out of his bad patch. I hope that he will recover very quickly.
"And of course it's not easy for me when you have a friend in the other side of the court showing an injury or crying. It was really a bad moment for both, but I wish all the best to him
"I tried to find good words for that moment. I said to try to be calm. Try to think about his family, his baby.
"I think he has everything to fix this problem and come back on tour stronger."
