Alex Bolt will be given a WC to main draw which means that Jay is in if he plans to travel.
Tomic has also said he is not going to play, so Jay would be comfortably in. Bit late to travel and acclimatize now though. I doubt Jay will make the trip.
It's a bit of a strange one since Jay was entered in Bangkok for week 1 until a late withdrawal ( with another Bangkok Challenger as an alternative for week 2 ) and I'd say the odds from the time the qualifying entry list came out were that he'd get in if maybe tight, though in the last few days it became almost certain.
I know it was said that he was in the UK on his Dad's 60th birthday, but in all the circumstances I do hope that he is fit and well.
He's still apparently on the Aussie list for now. Having remained on the list at all at least indicates original interest.
