"Not the result I wanted, would have loved to continue my run here, but today it wasn’t possible," Nadal posted to Instagram. "Mackenzie played at a great level and I wish him the best for the rest of the tournament.

Nadal pulled up in the second set against McDonald, leaving the court for medical treatment before returning. The 36-year-old was clearly hobbled and lost in three sets. 

"It's a tough moment. It's a tough day," Nadal said. "I can't say that I am not destroyed mentally at this moment, because I would be lying."

It’s the second time in three grand slam tournaments that an injury has impacted Nadal’s final result.

At Wimbledon over the summer, Nadal was forced to pull out of his semifinal match against Nick Kyrgios due to an abdominal strain.

"Sometimes it’s frustrating. Sometimes it’s difficult to accept," Nadal said after his Australian Open loss. "Sometimes you feel super tired about all this stuff, in terms of injuries."
