To be fair Bhunu is better than her current ranking suggests. She has a career high just inside the top 500 and won a 15K held at the same venue a couple of weeks back.
Yes, I see the career high was November 2016 - and she didn't play for nearly three years. This year she is 27-6, so playing a lot of matches, but mainly in qualifying - hence no current WTA ranking. I resue the points for that W15 win will go on next week.
