Players wanting to play doubles but don't have a partner write themselves on a list, from where they together with the office can try to match up. Scheepers is a decent doubles player and a good match up.
I do however, again, think that Mandy should take it easy on the doubles and really focus on singles.
This year Mandy have scores a little less than 400 point. To assure entry into Australian Open 2014 she need about 650 point by end of november. That leaves her needing about 250 point scored the rest of the year.
You could say that Australian Open has started and a high scoring US Open are not to be missed at any cost.
