Interesting to see at least two teenagers make it into the fourth round. Tomljanovic (back, finally, from injury and looking very good again - another Croatian!) over Petkovic; and very strikingly, Muguraza over Wozniacki 6-2 6-4!
Lauren Davis also still has a chance - there may be others, I didn't look.
It's moving time amongst Laura & Heather's generation it seems, with several others (M'lady especialy, and Beck) recently powering on.

My earlier prediction is looking quite good - that rarely happens.
Often in these doubles matches I think if a team wins the first set and goes behind early in the second, they tend to give it up quite easily and save themselves for the deciding tie break.
