After this result I almost hope that the reason was medical.
The only thing we can be sure is that this mini tour of Asia gave Petra's new coach a good insight on what to do in the off-season. Let's just hope he's got a good plan. AO MD should be secure now, but we won't know until we see how many girls pass Petra in the rankings and how many withdrawals there ends up to be in Melbourne next year. But right now I think that should be the least of worries of team Martic. They sure have a job ahead.
