I was more worried about her match than Beth's, in fact, despite the ranking difference - youngsters are unpredictable whereas Heise is more of a known quantity. Great to see Sam on form.
Both Sam and Beth have doubles matches today too. Sam is playing her QF match now with Thandi, a set up and break down 6-3 2-3*
In the absence of Olivia (and Alicia), Beth is playing her L16 match with Karen Barritza (DEN) her partner this week.
