Just too sad that such things happen to him whenever he was on a good run.
Of course this doesn't happen in a Mickey Mouse tournament after he reached the 2nd round... no, always before big matches...
but the positive thing is hopefully that it's "only" the neck and not again a wrist, leg problem, something like that... I hope he can get help soon for it, that should be possible. A good Wimbledon result would also be important, the 4th round of Roland Garros is a nice bonus, but the 1st Wimbledon round loss that stands so far in his Entry Ranking could need a bit improvement and on grass this should be possible I hope.
Get well soon Kiwi! really very bad luck!
