Nole was forced to retire from his match against Filip Krajinovic due to, I assume, his allergies and respiratory issues.
I went to law school in a farm town. If I came outside during the Spring and saw a yellow film on my car, I immediately turned around and went back inside my apartment. There was no way in hell I was going to deal with that much pollen in the air. I also hated school so, there was that.
Sucks for Nole. No reason he'd want to withdraw or retire from his home tournament. If it's really allergies is there a reason he should withdraw from Madrid? Isn't that an indoor tournament?
