Damn, it's really very disappointing that another tournament is gone now.... and that Kiwi has to retire... I'm really sad about the retirement, I hope it was just a bad day for him and that the heat was killing him or anything like that... normally he is very fit and doesn't mind playing in the heat, but you can have such days.
On the positive thing about all this retirement: at least it appears he has no broken bones or raptured ligaments or anything like that!!
These breathing problems can be over after two hours, tomorrow... much faster than most other kinds of injury
