Ok let me jinx Boulter real quick but Jorovic feels like a...better match up than Danilovic? How rogue from Serbian captain
It definitely does seem more favourable. I assume it was just because she is higher ranked, but it was Danilovic who faced the Georgian #1 (circa 150), whereas Jorovic beat British based Bolkvadze who is about 300 odd in the rankings. Harriet obviously beating Jorovic in that Aussie Open FQR as well.
I was originally thinking Olga might beat Katie B and Jo might get the better of Krunic and it would come down to the doubles, but a bit more optimistic now. Mind, in reality, Boulter and Jorovic probably match up quite evenly, but just the latter hasn't had as many opportunities to increase her ranking this past year.
Serbia seem to have rotated their players all week so they will have had more rest, although they've only used three players including the doubles. I think it's been a big ask for Katie and Jo to play singles on all 4 days.
