I'd guess they both want to get back, mid-week, if they lose the singles, and don't want to commit to maybe having to stay around for the doubles till the end.
Glad to see Freya stopped the rot, and thanks too to Steven for the kind tidying up (meaning he deleted his comment a bit earlier, not mine, when we both posted the same update simultaneously!).
The qualifiers still have to be placed in the draw, as far as I can see, which means Harriet still doesn't have her R1 opponent for tomorrow, Wed, and one of Freya's potential R2 opponents will also be a qualifier.
