King won their only previous meeting. That was in an Australian ITF hard court tournament in February this year. She won in 3 sets after losing the opening set 6-4.
Zhang has been playing well in ITF hard court tournaments this year. This week she started slowly in her first match but fought back from losing the first set against Jorovic. She was fairly strong favourite in the last round but both sets were tight.
King has been in decent form lately but has not been tested this week. She was broken just once in each of her matches.
Their stats on hard courts are quite even with King having a slight edge in hard court matches this season and Zhang being ahead in their last 10 matches on this surface.
I think Zhang can take this to 3 sets. I will look to lay King if she breaks first.
