The wild card play-off in China is only for Asian players, the winner of which gets a wild card into the AO. There is another separate wild card playoff held at the beginning of December at Melbourne Park for the Australian players, generally for those players ranked under 250 plus others by invitation from Tennis Australia.
Imo Saville will get invited, but the list of other promising juniors is getting long now.
Yeah, that's the one I was thinking of (usually watch it) but when I googled for info I saw the Chinese one and thought that they may have moved the location to promote the whole slam of Asia-Pacific angle.
Maybe the increase in promising Australian's can help Luke in the long run. There would probably be more being made of his poor year if not for the success of other young players taking the attention. Of course, it makes it tougher for him to pick up ranking points in Australian tournaments and to get wildcards but it's probably better for him to face tough competition from within the country rather than being a big fish in a small pond and then struggling when he plays better players.
The big problem is confidence. Like you said earlier, he needs to get that winning feeling.
