Korpatsch really played great clay court tennis those last two sets. She really went for her shots when she could. Thats a a great step for her since she mostly went back to extremely passive tennis in the past when the opposition was strong or she became nervous.
As always though if she wants to progress on other surfaces as well she really needs to further work on her serve. Its better already but she will still get killed by big returners on faster surfaces with that kinda 2nd serve.
